Cavity Filter（RSC-B2442-72PA）

Product Introduction:

The RSC-B2442-72PA is a compact 2.4 GHz RF bandpass filter designed for reliable signal selection and interference suppression in wireless communication systems. It features a center frequency of 2441.75 MHz and a 72 MHz bandwidth covering 2406–2478 MHz, with insertion loss of ≤3.5 dB, passband ripple below 2.5 dB, and VSWR of ≤1.5:1. The filter provides strong out-of-band rejection, reaching ≥30 dB attenuation at ±92 MHz, ≥50 dB at ±142 MHz, and ≥70 dB at ±250 MHz from the center frequency. With a standard 50 Ω impedance, compact 35 × 24 × 9 mm package, 2-pin interface, and an operating temperature range of -40°C to +70°C, it is well suited for compact and robust RF system integration.

With its 2406–2478 MHz passband and high out-of-band attenuation, the RSC-B2442-72PA is suitable for 2.4 GHz ISM-band wireless equipment, RF front-end modules, wireless communication devices, IoT gateways, industrial wireless systems, and other applications requiring effective band selection and suppression of unwanted adjacent or out-of-band signals. It can be integrated into transmitter and receiver signal paths where stable 50 Ω matching, compact size, and reliable filtering performance are required, making it a practical RF filtering solution for communication modules, embedded wireless equipment, and professional RF systems.
