Spectrum Compatibility Interference Analysis





Our line of PowerMatch Filters have been designed with the most demanding RF co-site interference applications in mind. A key advantage of PowerMatch Filters is its ability to sustain maximum stopband rejection independent of its load impedance termination. PowerMatch Filters are offered in band pass, band stop (notch), low pass, and high pass configurations as well as customized combinations such as band pass with integrated notch. PowerMatch Filters are protected by multiple patents and/or pending patents.

Here is a sampling of our available PowerMatch Filters:

P/N Filter Type Stopband Range (MHz) Rejection (dB) Insertion Loss (dB) Power Handling (W) VSWR

Custom Co-Site Solutions

We have worked with customers to develop custom, integrated co-site solutions. For example, the TS6208 is an intelligent RF sub-assembly designed for UHF TACSAT applications. This transmit/receive module autonomously switches between a high-power handling transmit and a low noise receive mode without external user command. Further, the unit has built-in overload protection by automatically switching into a low-loss bypass mode upon detection of excessive RF power.

If you are interested in our products, please contact us by email at sales@terasystechnologies.com or by phone at 808.469.4251. We will be happy to discuss your requirements and how we can tailor our solution for your needs. We can synthesize a design for you, providing an information package containing s-parameter files, mechanical drawings, and electrical specifications.



Our products are ideal for situations where the interference problem is adequately understood and defined. In other cases, TeraSys Technologies offers radio frequency (RF) co-site interference analysis (CSIA) services to help our customers understand their interference situation and needs. Whether designing systems from the ground up or investigating those already in place, CSIA is necessary for the cost-effective design of multi-antenna systems, helping to identify sensitive and critical interference paths. CSIA is TeraSys' proactive approach to preventing costly long-term consequences by optimizing design goals or mitigation solutions upfront.

Measurement and Assessment

For deployed systems, we can measure and assess the interference situation, providing a description and visualization of the spectral landscape. Our experience spans a variety of scenarios on different scales, from larger geographical spaces (e.g. base stations in a metropolitan area) to human-scale platforms (e.g. multi-radio vehicles). In any scenario, we work with our customers to meet their needs, collaborating to craft a thoughtful plan based on required accuracy, budget, and schedule prior to execution. While each project is uniquely scoped, there are basic components to our service.

  • Capture

    We take empirical measurements of the spectral environment, capturing the necessary data to assess the interference situation.

  • Visualize

    In addition to numerical results, data visualizations are created to help make sense of the measurements. Examples of these visualizations include spectral plots as well as spatial overlays of electromagnetic and geographical data.

  • Assess

    Leveraging our measurements and analysis, we help our customers understand their current interference situation. More importantly and if necessary, we help to identify key actionable steps that may include re-design, mitigation products, or further analysis.

Modeling and Simulation

Even to experienced engineers, optimal radio and antenna placement may not be obvious. With all but the simplest of configurations, empirically determining optimal configuration for acceptable performance can be cost prohibitive, labor intensive, and time consuming. Electromagnetic interference modeling and simulation offers an economical, risk-reducing approach to multi-antenna RF systems.

Our CSIA modeling and simulation process includes a true 3D electromagnetic analysis service that provides not only graphical and numerical results, but also offers a root-cause explanation of why the interference is occurring, enabling the Customer the opportunity to make informed decisions of their interference mitigation options.

Typical Customer Deliverables

While each Customer may desire slightly different analytical outputs, our most requested data outputs include the following:

  • Heat maps

    A heat map, or coverage map, is a two-dimensional spatial representation of radio communications strength as a function of distance. These maps are typically used to visualize a receiver's performance with and without RF interference.

  • Field plots

    Electromagnetic field plots are sometimes instructive to assist the Customer in the visualization of how the energy is propagating from one antenna to another to efficiently assess how to best mitigate the RF Interference. These plots are sometimes referred to as "near field" plots.

  • Tabular results

    For CSIA scenarios that involve multiple antennas, an "interferer/victim" analysis matrix is often provided to enable the Customer to quickly visualize which configurations of antennas are subject to the greatest degree of RF Interference, allowing them to efficiently focus their optimization efforts.

  • Interference impact analysis

    As domain experts, we can not only identify interference issues, but also understand them. We are fully versed in the interference mechanisms and impacts to transceivers. We enable our Customer to understand why they are experiencing interference and what can be done about it.




Visiting Us

Who We Are

TeraSys Technologies is an SBA certified 8(a) small disadvantaged business founded in 2007 with core competencies in wireless interference analysis and developing custom mitigation solutions. We are headquartered in the beautiful state of Hawaii and located in the heart of downtown Honolulu's business district.

Our Vision Statement

To be a world-renowned elite team that offers an unforgettable Customer Experience through Innovation and the Aloha Spirit.

The Urgent and Compelling Need for Innovation

We pride ourselves on solving our Customer's toughest challenges which often means we are called upon to develop solutions that do not exist. This is why we expend a significant amount of effort designing our working environment to allow us to innovate.

We define innovation as "the act of combining creativity and problem solving to make something new and useful." We use this definition as our yardstick to ensure that our products are not only unique, but also offer a solution to a problem in demand as opposed to products that may be novel yet are solutions looking for a problem to solve.

Our work spaces are laid out to encourage collaboration and information sharing including multiple tools for communication. We regularly consult with technical experts in adjacent fields to increase our situational awareness of new and emerging trends. And we are constantly engineering our innovation processes, working to come up with new and better ways of innovating.

We recognize that defining innovation and creating the infrastructure to support it may not succeed unless each member of our team lives and breathes innovation. So each member of our team must display the desire and ability to innovate regardless of their functional role. Innovation is so important to us that everyone is required to perform at least one innovation per year to make sure that we all "live the innovative lifestyle."

Leveraging the Brand Recognition of Aloha

Being headquartered in Hawaii provides us with a unique opportunity to leverage one of the world's best known brands, the Aloha Spirit.

Aloha is uniquely associated with Hawaii and evokes images of paradise, generosity, and hospitality. We have designed our Customer Service policies to reflect the concepts and feelings of Aloha, making us able to offer our Customers unique, unforgettable Customer Service experiences that they cannot find anywhere else in the world.

Whether you come to our Hale (home) or we are visiting yours, rest assured you will never forget what it means to do business with TeraSys where you can enjoy the benefits of innovative solutions and world-class hospitality.

An Elite Team

We firmly believe in the power of the force multiplication when a team is filled with highly talented individuals bonded through shared core values and focused on a common goal.

We know that what we seek is not easy, because worthwhile things rarely are. We also know that there is no such thing as a universal company culture, only that there needs to be a match between our culture and you.

For those rare individuals that know your worth and seek the challenge of being part of a high performance team, we invite you to evaluate whether our culture fits you. If you find a resonance with us, then please contact us as we may be the team you have been looking for your entire career.

We enjoy the challenge of the unknown, setting the stage for innovation

This attitude is more than just being risk tolerant. This is an act of courage and humility to admit that we don't know something but are confident we will find the answer we need. We approach problems from a can-do attitude and seek to find the one way a problem can be solved as opposed to identifying the thousand ways it cannot.

Everyone is willing to work for the larger good in the name of teamwork

Teamwork is vital because today's problems are extremely difficult to solve by even the most talented individuals. Working together takes sacrifice and compromise and is a conscious act to do what is best for the many even if it may not be best for the one.


Excellence and quality are difficult to define but easy to recognize. We make sure everything that we do is recognized as excellent. Our products are the physical manifestation of our collective vision, planning, and execution.


We push to make ourselves and our products better today than we were yesterday. Professional growth has become a necessary survival skill in today's fast moving market, so we expect everyone on our team to constantly grow, and invest as many resources as we can towards this goal.


Repeat after me: "I am responsible for the results of my choices and actions both good and bad, even before I know what the outcome is going to be." Accountability and trust are intimately linked in the dynamics of a team, so we remain constantly vigilant to make sure that everyone on the team from the President to managers to staff members are held accountable for their part of our collective success.
