About
The WiRan S-Band Diplexer (DSx family, ordering codes DSA and DSB) separates uplink and downlink S-band signals for CubeSat communication systems, offering minimum 75 dB (typical 80 dB) isolation between TX and RX paths. DSA covers 2025-2068 MHz (RX/uplink) and 2200-2245 MHz (TX/downlink); DSB covers 2067-2110 MHz (RX/uplink) and 2245-2290 MHz (TX/downlink). Insertion loss is below 1.2/1.5 dB across the band, power handling reaches 2.5 W, and the unit operates from -40 to +75 degC. Both variants share the same compact 80x80x29 mm, 220 g housing with SMA female connectors, and are TRL9 flight-proven for nanosatellite platforms.
