A DIVISION OF MYSTERY MANUFACTURING

Experience behind
every signal.

We’re bringing together experienced engineers and RF specialists approaching retirement, creating a place for them to do some of their best work—on their own terms.

With individual careers spanning 15 to 40+ years in RF development, our growing team brings decades of knowledge to custom development challenges. We’re building this division around their expertise, giving them control over the direction of their work and the opportunity to create something they’re proud of before retirement.

At Mystery Manufacturing, we provide the support to bring the team together and turn their ideas into working results.

15–40+years of individual
RF experience across the team

RF power.
Beyond the horizon.

Understanding the amplifier.
Understanding the whole link.

RF power amplifiers

Radio-frequency power amplifiers take a low-power RF signal and raise it to a level suitable for transmission. They sit near the output of a transmitter, supplying energy to an antenna while preserving the information carried by the signal. Their design affects range, signal quality, electrical consumption, and the heat a system must manage.

Good amplifier development balances output power, operating frequency, bandwidth, efficiency, and linearity. More power alone does not guarantee a better link. Distortion can spread energy into unwanted frequencies, while inefficient operation adds thermal load. Matching, biasing, protection, cooling, and the surrounding power supply all influence how an amplifier behaves in a complete system.

Troposcatter technology

Tropospheric scatter, or troposcatter, uses a small portion of radio energy scattered by variations in the lower atmosphere to communicate beyond the normal radio horizon. Directional antennas at two sites illuminate a shared region of the troposphere. A receiving system recovers the weak scattered signal, allowing communication without a satellite in the path.

Because only a fraction of the transmitted energy reaches the receiver, troposcatter links require careful system planning. Antenna gain, transmitter power, receiver sensitivity, terrain, climate, and the required availability all matter. Propagation conditions vary, so link budgets and appropriate fading margins are essential. Actual performance depends on the specific route and equipment; an illustration cannot establish achievable range or capacity.

For a custom development project, the starting point is a clear requirement: frequency band, target power, waveform, duty cycle, operating environment, and the intended interface to the rest of the system. From there, engineering work can define an approach, evaluate trade-offs, and plan measurements. MM RFS Development welcomes conversations about RF power amplifiers and related development challenges, with project scope and deliverables agreed before work begins. This keeps expectations grounded in measurable requirements and a shared understanding of the intended application.
