Product Introduction:
The RSL-N1470-100SA Notch Filter is a compact, high-performance RF filter engineered to suppress unwanted signals in the 1420–1520 MHz frequency band while maintaining excellent transmission performance in the passbands. It delivers ≥30 dB stopband rejection, ≤1.3 dB insertion loss, 50 Ω impedance, and VSWR ≤1.8:1, ensuring stable signal integrity and minimal system loss. With a miniature 17 × 12 × 4.5 mm footprint and a wide operating temperature range of -40°C to +70°C, this filter is well suited for space-constrained and demanding wireless communication systems.
Typical Applications
The RSL-N1470-100SA notch filter is ideal for eliminating interference in RF and microwave systems where reliable signal isolation is critical. It is widely used in wireless communication equipment, RF front-end modules, base stations, telecommunication infrastructure, test and measurement systems, industrial wireless networks, and custom RF integration projects. By effectively attenuating unwanted signals within the designated stopband while preserving low-loss transmission across the operating passbands, it helps improve receiver sensitivity, system stability, and overall communication performance.
