What does the nasal cavity filter for 2878-2882MHz?

Chengdu, September 22, 2025 – Keenlion Microwave Technology completed the first production run of its 2878-2882 MHz cavity filter last month. Designed for small cell and IoT radios, this compact filter transmits signals in the 2.48 GHz band without leaking into the adjacent ISM band. Each 2878-2882MHz cavity filter is scanned on a 50 GHz PNA-X and shipped with a signed test curve demonstrating insertion loss below 1.0 dB and standing wave resistance below 1.5 dB across the entire 4 MHz band.

Compact Advantage

Measuring only 74 × 31 × 30 mm—smaller than a sugar cube—the 2878-2882MHz Cavity Filter handles 20 W CW. Two M2 holes on 15 mm centers allow the 2878-2882MHz Cavity Filter to disappear into UAV pods, handheld radios, or compact DAS remotes where space is measured in millimeters.

Advanced Manufacturing Capabilities

Manufactured in Keenlion's ISO 9001-certified production facility in Chengdu, the 2878-2882MHz Cavity Filter benefits from the company's vertical integration and extensive manufacturing expertise. "Our new 2878-2882MHz Cavity Filter incorporates several proprietary manufacturing techniques that enhance performance while reducing physical dimensions," explained the company's Chief Engineer. The production process for the 2878-2882MHz Cavity Filter includes automated CNC machining, precision tuning, and 100% VNA testing to ensure consistent quality.

Availability and Customization

Keenlion is now accepting volume orders for the 2878-2882MHz Cavity Filter, with sample units available for qualified customers. The company's engineering team can provide customized versions of the 2878-2882MHz Cavity Filter to address specific application requirements, maintaining the company's reputation for flexibility and customer-responsive manufacturing.
