K/KA-BAND transponder

Miniaturized non-regenerative transponder designed for cubesat and small satellites for leo and geo applications.


A miniaturized non regenerative transponder designed for CubeSat and Small Satellites for LEO and GEO applications.

With a volume of 1 U and a mass of 1.2 kg, the transponder operates in Ka-band and it is characterized by low power consumption.

The transponder analog bandwith can be customized from 400 kHz to 200 MHz.
The radio can operate with the most common modulation schemes and offers a versatile beacon function.

Telemetry and Telecommand functions are available over the common standards.
