About
The WiRan X-Band Diplexer DXB variant provides the same full-duplex X-band capability as DXA (7145-7235 MHz RX / 8350-8500 MHz TX) but with SMA female connectors instead of SMP, and was designed under the supervision of the European Space Agency for CubeSat Earth Observation missions. DXB achieves minimum 80 dB (typical 95 dB) isolation between TX and RX, insertion loss below 1 dB (typical 0.75-0.85 dB), and return loss better than 17 dB (typical 23 dB). Rated for 15 W CW power handling and a wide -75 to +90 degC operating range, it weighs 70 g in a 96x96x15 mm housing.
