Triad RF Systems

CubeSat and SmallSat

Closing a Low Earth Orbit link across hundreds of miles is challenging, and the difficulty only multiplies as CubeSats become tasked to provide increasing amounts of bandwidth and data rates across limited-spectrum links. The relatively short mission lengths of CubeSats allow for their radio systems to be continually upgraded and deployed at a much faster rate than traditional large satellite deployments. RF subsystem technology must keep pace. That’s why Triad’s engineering team remains adept at designing for the rigors of the CubeSat environment. In addition to designing in advance for lighter weight and tighter requirements, we perform the requisite analysis to ensure each RF amplifier and radio system we deploy passes all pre-flight requirements.


Triad further expanded their product line to provide RF amplifiers and subsystems for CubeSat payloads. These include extremely efficient, ultra small, power amplifiers, BUCs, and complete bi-directional RF sub-systems in UHF, S, and X band. We have recently upgraded our RF labs to support mm-Wave design and test, and are currently designing micro-size, Ka band BUCs and Tx/Rx modules for advanced CubeSats. These assemblies are circuit card form factors that fit up/down conversion, RF filtering, amplification, LNAs and switching in unprecedented package sizes of low size, weight, and power to achieve SWaP objectives.
