UHF/UHF Transceiver

The PULSAR-UTRX is a compact telemetry and command radio designed for nanosatellite missions, compatible with the CubeSat standard with a CubeSat kit PC/104 form factor.

It operates UHF uplink and downlink serving both commercial and amateur frequencies. Featuring a beacon and DTMF backdoor, the PULSAR-UTRX offers unparalleled reliability in flight.

PULSAR-UTRX implements 9600 bps GMSK and 1200 bps
AFSK and operates in a half-duplex mode. A combination of AFSK and GMSK is configurable for transmit and receive. These modes are selected as an I2C command and the default mode will be selected if a reset occurs. The default mode can be requested at time of production.

  • UHF uplink, UHF downlink
  • Transmit output power adjustable from 27 to 33 dBm
  • Adjustable in 3 dB steps
  • 9600 bps GMSK, and 1200 bps AFSK data rates
  • Compatible with the CubeSat standard with a CubeSat kit PC/104 formfactor
  • Robust lower data-rate back-up radio for a higher data-rate radio
  • Implements AX.25 protocol encoding/decoding with transparent mode with optional convolutional encoder
  • With DTMF backdoor
  • Inactivity beacon
  • low-power Flash-based FPGA
  • Transparent mode with optional convolutional encoder
  • Serving both commercial and amateur frequencies
