The AAC SpaceQuest TRX-U is a compact single board transceiver for satellite communications in the UHF Band. Designed for CubeSat and SmallSat missions our high-performance TRX-U satellite UHF transceiver is ideal for space missions where a low data–rate uplink and downlink are required and can be used as a robust lower data-rate back-up radio for a higher data-rate radio.
With up to 8 programmable channels, which can be custom programmed, this solution has been designed for ease of use and offers transmit and receive frequencies covering both amateur and commercial bands. The flight-proven TRX-U is an ideal satellite TT&C Radio or Narrow Band Communication Payload for CubeSat and SmallSat missions.
These units have been extensively tested and are in use by clients around the world. They have been deployed on orbit in various configurations for close to two decades of successful operations.
Frequencies
With UHF uplink & downlink the TRX-U serve both the commercial and amateur frequencies respectively
Custom Configuration
With 1 to 8 Channels, which can be custom programmed in 300 Hz Steps. With transmit/receive data rates of 2.4 and 19.2 Kbps this solution is highly adaptable to meet your mission needs.
