CPI Diplexer 110800-11

CPI 110800-11 C-Band 2-Port Diplexer | Circular | 3.625–4.2 GHz Rx / 5.85–6.425 GHz Tx

The CPI 110800-11 is a circular-polarized 2-port C-band diplexer designed to separate transmit and receive paths with high efficiency. It supports 3.625–4.2 GHz for reception and 5.85–6.425 GHz for transmission with low insertion loss and ≥60 dB isolation. Built to withstand 5 kW CW power and pressurized to 2.0 PSIG, it’s ideal for high-power SATCOM gateways and uplink/downlink systems.
