We’re a factory. So when we say stable insertion loss and three‑zone blocking, you know we actually control the process. Need custom dimensions or different connectors? Just tell us – we do that every day.
Take our 4100-4480MHz Cavity Filter. It handles real RF work, not just spec sheets. Insertion loss? ≤1.0dB. Rejection? 95dB where it matters. What does that mean for you? Your signals stay clean – even when the bands are packed with noise.

4100-4480MHz Cavity Filter Details

The passband covers exactly 4100~4480MHz, matching high‑frequency communication systems. You get ≤1.0dB insertion loss, so you won't waste signal strength. Rejection reaches 95dB on two critical out‑of‑band ranges (DC‑3800MHz and 4780‑5100MHz, with another 60dB from 5100‑8500MHz). The housing is machined from solid aluminum for long‑term durability. Impedance is standard 50Ω to work with most equipment. Power handling is 50W.

And because we are a real factory, Keenlion customizes each 4100-4480MHz Cavity Filter. Need a different connector, slightly shifted rejection, or non‑standard dimensions? Just tell us. We'll tune it to your system, not the other way around.
