0.5-1.5MHz/4.5-12MHz/12-30MHz/80-110MHz BPF

0.5-1.5MHz/4.5-12MHz/12-30MHz/80-110MHz Band Pass Filter

The 0.5–1.5MHz / 4.5–12MHz / 12–30MHz / 80–110MHz Band Pass Filter is a compact multi-band RF filter designed to improve receiver performance by passing only the desired frequency ranges while suppressing out-of-band interference. Featuring four independently filtered bands, low insertion loss, and 50-ohm impedance, it is ideal for SDR receivers, spectrum analyzers, HF receivers, and RF laboratory applications.
