About
A miniaturized non-regenerative bent-pipe transponder designed for CubeSat and small satellites for LEO and GEO applications. With a volume of 0.5 U and a mass of 700 g, the transponder operates in K/Ka-band and is characterized by high performance and low power consumption.
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 60 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 programmable oscillator frequency correction.
