About

A miniaturized non-regenerative transponder for CubeSat and small satellites, operating in Ku-band for LEO and GEO applications.

The transponder analog bandwidth can be customized from 400 kHz to 500 MHz. The receiver and transmitter can be tuned independently and the gain can be set in a 30 dB range as fixed (FGM) or adaptive with automatic gain control mode (AGC). The transponder offers a versatile CW beacon mode as an option.

Applications: LEO small satellite services and GEO satellite services. Additional features include in-orbit firmware updating and an optional CW beacon mode.
