2878-2882 MHz Customized Cavity Filter Manufacture RF Filter
Keenlion’s 2878-2882MHz Cavity Filter leverages temperature-stable plated aluminum cavities to achieve ultra-steep rejection ( ≥40dB at ±5 MHz offset). The filter’s compact housing (30% smaller than industry averages) ensures easy integration into space-constrained systems without compromising performance. Its low insertion loss (≤1dB) maximizes power efficiency, while the VSWR of ≤1.5:1 minimizes signal reflections, critical for phase-sensitive applications like 5G base stations and radar altimeters. Each 2878-2882MHz Cavity Filter undergoes 100% automated VNA testing to validate specifications under MIL-STD-810 environmental conditions .

Company Information
Sichuan Keenlion Microwave Technology is a Chengdu-based manufacturer with twenty years of passive components expertise。 20 years of second-shifts taught us how to mill walls to ±0.02 mm so the 2878-2882MHz Cavity Filter resonator sits air-tight; that discipline lets the 2878-2882MHz Cavity Filter sail through desert base-stations and North-Sea radar racks without a drift.
