CPI Diplexer 110230-26

CPI 110230-26 Ku-Band 4-Port Diplexer | Circular Polarized 

The CPI 110230-26 Ku-band diplexer is a high-performance 4-port waveguide assembly designed for circularly polarized satellite systems. Operating over 10.7–12.75 GHz (Rx) and 17.3–18.4 GHz (Tx), it delivers excellent port-to-port isolation (≥85 dB) and supports up to 3 kW CW transmit power. With low insertion loss, wideband axial ratio, and robust pressurization, it is ideal for earth station uplink/downlink systems.
