LC Band-pass Filter（RSL-B530-420SA）

Product Introduction:

The RSL-B530-420SA 530 MHz LC band-pass filter is designed for reliable wideband RF signal selection across 320–740 MHz, with a nominal center frequency of 530 MHz. It delivers low insertion loss of ≤1.8 dB, passband ripple below 1.5 dB, and VSWR of ≤1.8:1 in a standard 50-ohm system. With out-of-band attenuation of at least 63 dB from DC to 150 MHz and from 910 to 2000 MHz, the filter effectively suppresses unwanted low- and high-frequency interference. Its compact 14 × 7.9 × 3.8 mm package and wide −40°C to +70°C operating temperature range make it suitable for space-constrained and demanding RF equipment.

Typical applications include UHF communication systems, RF transceivers, wireless infrastructure, telemetry equipment, signal repeaters, spectrum monitoring devices, test and measurement instruments, and custom RF front-end modules. The broad passband supports systems that need to transmit or receive signals over a wide UHF frequency range, while the strong rejection characteristics help improve receiver sensitivity, reduce adjacent-band interference, and protect downstream amplifiers and mixers. The RSL-B530-420SA is well suited for OEM integration, industrial wireless products, communication terminals, and other B2B applications requiring a compact, low-loss 530 MHz band-pass filter with stable broadband performance.
