Device Overview

General Description

The MFBP-00062CSP3 passive MMIC surface mount bandpass filter is an ideal solution for small form factor, high rejection filtering. The MFBP-00062CSP3 features a 27.5-29.9GHz 1dBc passband and 2.8dB center frequency insertion loss. Passive GaAs MMIC technology allows production of smaller filter constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances allow for less unit-to-unit variation than traditional filter technologies. The MFBP-00062CSP3 is available as a 3.5 mm CSP3. Low unit to unit variation allows for accurate simulations using the provided S2P file taken from measured production units. For a wider bandwidth option, please see MFBP-00128CSP3. If higher rejection is required, see MFBP-00129CSP3.
