Mini-Circuits Ceramic Resonator Band Pass Filter, 1160 - 1400 MHz, 50Ω CBP-1280F+

CBP-1280F+ is a surface mount bandpass filter using coaxial-ceramic resonators, designed for L-band applications in aviation, defense, and radio astronomy systems. It operates with a center frequency of 1280 MHz and a passband from 1160 to 1400 MHz, maintaining a typical insertion loss of 1.0 dB and VSWR of 1.5. The filter provides at least 20 dB rejection in stopbands below 1000 MHz and above 1570 MHz. Housed in a shielded KV1710 package, it supports operation from -40°C to 85°C and can withstand up to 1 W RF power input. The part is RoHS compliant and features a six-pole design for good selectivity.
