Product Description
This is a cavity filter designed for UHF communication systems, which covers frequency range 429–448MHz. It achieves low insertion loss ≤1.0dB with passband ripple controlled within ≤1.0dB and return loss ≥18dB to guarantee superior impedance matching.
The filter provides outstanding rejection performance of 50dB at DC-407MHz and 50dB at 470-6000MHz, thoroughly blocking out-of-band interfering signals. With standard 50Ω impedance, it supports up to 100W RMS power handling, and works stably within the temperature range of -20°C to +85°C.
Mechanically, it adopts a silver-plated compact chassis with dimension 139mm × 106mm × 48mm (55mm Max height). Equipped with N-Female RF connectors, it is convenient for flexible system assembly. All raw materials comply with RoHS 6/6 environmental standard.
Suitable for public security intercom base stations, emergency wireless communication equipment, UHF radio transceivers and IoT signal filtering systems.
Customization service: As a professional RF passive component manufacturer, we offer customized frequency bands, power capacity, connector types and mechanical dimensions to match your unique project demands. Three-year warranty: Supported by 3-year quality warranty to secure long-term stable operation and full technical after-sales support.
