BBFCG1-252+

Product Overview

BBFCG1-252+ is a 1:1 LTCC balun bandpass filter for 2.4 GHz-class radio front ends, specified across 2.4 GHz to 2.5 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 50 Ω / 50 Ω; the published electrical data lists 12° phase difference, 3.5 dB max insertion loss and 7.5 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.
