Ceramic Bandpass Filter（RSG1425F350DCA）

Product Introduction:

The RSG1425F350DCA 1425MHz RF bandpass filter is designed for high-performance L-band signal filtering in compact RF systems. It features a 1425MHz center frequency with a wide 1250–1600MHz passband, low insertion loss of ≤2.5dB, ripple below 1.2dB, and stable impedance matching with VSWR ≤1.6:1. With group delay below 15ns, strong out-of-band suppression of ≥40dB from DC to 1150MHz and ≥30dB from 1700 to 2500MHz, and a standard 50Ω impedance, this filter provides reliable signal selection, interference rejection, and stable RF performance across a -40°C to +70°C operating temperature range.

This 1425MHz L-band bandpass filter is ideal for wireless communication systems, RF front-end modules, telemetry equipment, GNSS-related receivers, satellite communication devices, RF signal monitoring, industrial electronics, and laboratory test instruments. Its broad passband and high rejection capability help isolate desired L-band signals while reducing unwanted noise, harmonics, and adjacent-frequency interference, making the RSG1425F350DCA a reliable choice for B2B RF, microwave, and communication system integration.
