Device Overview

General Description

The MFBP-00165GSM1 surface-mount bandpass filter is an ideal solution for extremely small form factor, high rejection filtering. The MFBP-00165GSM1 features a 0.8-1.6GHz 1dBc passband and 1.0dB center frequency insertion loss. Its advanced glass substrate technology allows production of smaller filter constructions that replace larger form factor circuit board constructions. Tight fabrication ensures tighter unit-to-unit consistency than legacy filter technologies, supporting accurate simulation with the provided S2P data. The MFBP-00165GSM1 is offered in a 4.25 x 7.5mm package.
