The Satlab SRS-3 is a full-duplex, low-power, S-band transceiver designed for TM & TC on micro- and nano-satellites.
The self-contained system operates on the ITU space operations S-band frequencies and features integrated transmit and receive filters, LNA and power amplifier, requiring only passive external antennas.
SRS-3 is highly configurable, with transmit and receive frequencies, bit rates, output power and framing configurations being adjustable on-orbit.
