BBFCG2-372+

Product Overview

BBFCG2-372+ is a compact LTCC balun bandpass filter with a 1:2 / 2:1 balanced-port transformation, specified across 3.3 GHz to 4.0 GHz. The device combines balun conversion and passband filtering in one small surface-mount component, so it is normally used near an RF transceiver, tuner, mixer or front-end module instead of as a standalone wideband transformer. The confirmed impedance specification is 2:1; the published electrical data lists 13° phase difference, 3.0 dB max insertion loss and 8.5 dB min return loss. This makes the part useful when a compact board needs a controlled differential RF interface while also limiting out-of-band energy around the target wireless band. Because the part is supplied in a 8-SMD, no lead package, replacement work should keep the exact order code, pad geometry and passband aligned with the original RF layout.

Applications

• 3 GHz to 4 GHz wireless front-end matching and band-limited differential RF conversion
• LTE/5G sub-6 GHz, CBRS, WiMAX or broadband RFIC interfaces within the published passband
• compact LTCC balun-filter stages where filtering and balanced-port drive are handled by one component
• BOM replacement where the passband, impedance ratio and 0805/no-lead pad layout must stay unchanged

Quality & Sourcing

Antrex Electronics can source BBFCG2-372+ for RF and wireless production, maintenance and BOM shortage requirements. For substitutions, compare the approved part number against the frequency range, impedance ratio, insertion loss, return loss, package style and RF layout before changing the BOM.
