Key highlights

The K/Ka-Band High-Speed LEO Radio provides a compact high-frequency transmit/receive radio for LEO satellite communications, combining a 17.7-20.2 GHz DVB-S2X transmitter with a 27.5-30 GHz DVB-S2 receiver. It is designed for missions that need efficient K-band or Ka-band SatCom links, high-order APSK modulation and flexible RF interfaces including 2.92 mm and WR28 waveguide options. With optional higher transmit power, compact 90 x 90 x 65 mm packaging and operation from -40 deg C to +65 deg C, it is suitable for demanding payload downlink, crosslink-style architectures and high-frequency satellite terminal designs.

Applications

K-band satellite communications, Ka-band satellite communications, LEO payload downlink, high-frequency satellite terminals, smallsat RF payloads, DVB-S2X transmitters, Ka-band receive links, commercial and government SatCom missions.
