Triad RF Systems has released a new solid-state power amplifier, the TA1165, designed to meet the performance and integration needs of CubeSat and SmallSat platforms operating in Low Earth Orbit (LEO). As small satellite deployments increase, the demand for compact, reliable, and flight-proven RF components has grown significantly—particularly for high-data-rate downlinks and inter-satellite communication.
The TA1165 is a Class AB GaN-based amplifier capable of delivering 20W of saturated output power across the 5.5 to 8.5 GHz frequency band, covering both C-band and X-band applications. It is built with a focus on minimizing size, weight, and power (SWaP), making it suitable for space-constrained platforms. The amplifier is compatible with a range of modulation schemes, including DVB and DVB-S2, and has demonstrated performance in actual LEO missions. It features a compact footprint (6" x 2.5" x 1.06") and weighs 482 grams, with a flexible 12–30 VDC input.
Key Features:
- 20W Output Power for long-range, high-throughput links
- Wideband Operation (5.5 – 8.5 GHz) for C-band and X-band support
- Flight-Proven in operational LEO environments
- Modulation Agnostic, with linear performance for DVB-S2 and other high-order signals
- Built-In Protections, including over/under/reverse voltage, thermal monitoring, and open load survivability
- SWaP-Optimized Design for small satellite platforms
The TA1165 is suited for a range of space communication applications. It can be used in LEO downlink chains to transmit payload data back to Earth, in inter-satellite links that support communication within satellite constellations, and in DVB-based systems that require high signal fidelity and minimal distortion.
