Product Description
This is a compact LC bandpass filter, a type of passive lumped component filter, with a center frequency of 300 MHz, covering the 285–315 MHz passband with a 1dB bandwidth of 30 MHz. It features a low insertion loss of ≤3.0 dB and a return loss of ≥14 dB, while delivering robust out-of-band rejection: ≥40 dB at DC–260 MHz and ≥30 dB at 330–2000 MHz, effectively suppressing unwanted interference.
Designed with 50 Ω impedance, this passive RF filter supports a power handling of up to 1W, making it ideal for low-power radio frequency filter applications in VHF/UHF bands.Mechanically, it is housed in a compact chassis measuring 50 mm × 20 mm × 15 mm with a black paint finish, equipped with SMA-Female connectors for straightforward integration. Built as a reliable custom lumped element filter, it uses RoHS 6/6 compliant materials, ensuring environmental compliance.
Customization service: As a professional RF filter manufacturer, we offer custom center frequencies, bandwidths, power ratings, connector types, and mechanical configurations tailored to your specific application requirements.
Three-year warranty: Backed by a 3-year warranty for guaranteed long-term stability and dedicated technical support.
