UDC400 is a fully integrated standalone transceiver module designed for Ka-band communication systems. The Transceiver operates as a wideband up/down converter when combined with a modem/ Software Defined Radio (SDR) to enable a fully functional Ka-band satellite communications system designed for use in Low Earth Orbit (LEO). 

This Transceiver offers up to 250 MHz of instantaneous bandwidth. On-board frequency synthesizers are able to lock to an external or onboard 10 MHz or 100 MHz reference signal are included on the Transceiver. The on-board reference signals are provided by high precision, low power consuming Temperature Compensated Crystal Oscillators (TCXO) with frequency stability of ±0.28ppm between -40°C to 85°C. The Transceiver is fully enclosed in an aluminium housing with SMP and SMPM RF connectors, DC Flying Leads for DC power and 6-Pin Pico-Lock connectors for DC power enable, PLL lock, current and temperature sensor connections.
