BLFCV-1570+

Product Overview

BLFCV-1570+ is a Mini-Circuits LTCC balun bandpass filter for narrow wireless front-end bands, specified across 690 MHz to 1.57 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 15° phase difference, 3.0 dB max insertion loss and 0.04 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.

Quality & Sourcing

Antrex Electronics can source BLFCV-1570+ 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.
