Triad RF Systems is a leading designer and manufacturer of integrated radio systems, RF power amplifiers, bi-directional amplifiers, assemblies and custom multi-functional amplifier systems for UAVs (unmanned aerial vehicles), drones and other unmanned systems.
With decades of accumulated expert knowledge in designing, manufacturing and servicing RF power components we offer a wide range of state-of-the-art solutions that push the limits of size, efficiency and linearity. Our high-performance products are ideal for aerospace, military and defense applications, particularly for the demanding environments of unmanned vehicle systems.
TRIAD Integrated Radio Systems
Rugged high-power radios for UAV communications
The Triad High Power Radio (THPR) series features high-data rate, long-range radio links for unmanned systems that are easy to integrate and deploy. Combining high-power RF subsystems with proven core radios, these rugged low-SWaP integrated radio systems are ideal for long-range UAS communications and military MANET (Mobile Ad Hoc Networking) applications.
Our THPR modules advanced active power control and equalization circuitry to prevent any possible drift issues, delivering ultra-stable RF output power and signal-to-noise ratio (SNR) and providing unmatched RF link robustness.
Triad High Power Radio systems can cover UHF, L, S, C, X and Ku bands, and are available in three different form factors for ultra-low-SWaP unmanned systems, rugged wheeled/tracked/maritime systems, or rack-mounted chassis applications in large unmanned vehicles. Our team of engineers and application specialists can provide full support, tailoring the radio to your unmanned system.
RF & Microwave Power Amplifiers (PA)
Rugged RF Power Amplifiers for UAV Applications
Our rugged solid-state RF power amplifiers are ideal for unmanned vehicle applications such as UAV data links. We select the best FET technology for the application, maximizing linearity while minimising DC power consumption and thus heat emission.
All of our power amplifiers have DC sections with advanced features including protection against over, under, and reverse voltage conditions. We also offer modules with our Versatile DC Supply (VDSTM) technology, eliminating the need for external DC converters and resulting in greater overall system efficiency.
In addition, we have integrated monitoring and control sections that are powered by microprocessor, FPGA and CPLD ICs. These provide functions such as RF power measurement, temperature monitoring, DC monitoring to the device level, and many other configurable alarms and warnings that can be tailored to the customer’s system requirements.
Our RF Amplifiers are available in frequencies up to 18 GHz, with bandwidths of 200-800 MHz for standard models and up to 12000 MHz for broadband. Custom-modified versions of these COTS amplifiers are also available upon request.

Bi-Directional Amplifiers (BDA)
Low-noise bi-directional RF amplifiers for UAV data links
Our low-SWaP (size, weight and power) bi-directional amplifiers are ideal for unmanned vehicle applications, such as extending the useful range of high-speed data links. These high-linearity, low-noise amplifiers are already in operation on several different unmanned aerial and ground vehicle platforms, including the Penguin B, Bat 12 and Shadow M2.
We use whichever FET technology (GaN, GaAs, or LDMOS) best suits the customer’s application, maximizing linearity while optimizing DC power consumption to preserve mission life.
Models operate in bands from 20 MHz to 8.5 GHz. Typical RF power values for the transmit section are 12/25 Watts of RF power for BPSK, 9/12 Watts for QPSK, 8 Watts for 16 QAM and 5 Watts for 64 QAM. The receive section features a low-noise amplifier with 11 dB of gain, with a typical noise figure of less than 2.5 dB.
