LC-Pass Filter（RSL-L900SA）

Product Introduction:

The RSL-L900SA is a compact high-performance low-pass filter designed for RF systems operating from DC to 900 MHz. It delivers low insertion loss (≤3.5 dB), excellent impedance matching (VSWR <1.8), and high out-of-band rejection (≥20 dB @ 930 MHz), ensuring reliable signal transmission while effectively suppressing unwanted higher-frequency interference. With a standard 50 Ω impedance, ultra-compact 12 × 6 × 4 mm package, and an operating temperature range of -40°C to +70°C, the RSL-L900SA is ideal for demanding industrial and commercial RF applications where stable performance and space-saving integration are essential.

Typical Applications

The RSL-L900SA Low Pass Filter is widely used in wireless communication equipment, RF modules, IoT devices, industrial control systems, telemetry, test and measurement instruments, radio transmitters, and embedded RF platforms. It is especially suitable for eliminating harmonic signals and reducing electromagnetic interference (EMI), helping improve overall system performance, signal integrity, and compliance with RF standards. Its compact SMT design makes it an excellent choice for high-density PCB layouts in OEM and ODM electronic products, providing engineers and system integrators with a reliable solution for modern RF signal conditioning.
