SST01: Secure FHSS Cubesat UHF Transceiver

From €4,500

The EXA’s SST01 is a highly integrated, low cost, 240/433/868/915MHZ wireless transceiver module. Designed for CubeSat and SmallSat missions, 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.

The very low receive sensitivity (–120dBm) coupled with industry leading +30dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance.


Additional system features such as an automatic wake-up timer, low battery detector, 64 byte TX/RX FIFOs, automatic packet handling, and preamble detection reduce overall current consumption and allow the use of lower-cost system MCUs. An integrated temperature sensor, general purpose ADC, power- on-reset (POR), and GPIOs further reduce overall system cost and size.
