What is the Insertion Loss of a Cavity Filter? Keenlion Confirms ≤1.0 dB for 975-1005 Hz Model

Keenlion’s newly released 975-1005 Hz Cavity Filter answers with an unequivocal insertion loss ≤1.0 dB across the entire 30 Hz bandwidth.In our ISO-9001 laboratory, 100 production samples of the 975-1005 Hz Cavity Filter were swept on a Keysight PNA-X. Every Cavity Filter recorded insertion loss values between 0.75 dB and 0.98 dB, well below the ≤1.0 dB specification. These results confirm that the Cavity Filter maintains ultra-low loss even under temperature extremes from ‑40 °C to +85 °C.

Design Excellence

The ≤1.0 dB insertion loss of this Cavity Filter is achieved through a precision-machined aluminum cavity, silver-plated resonators, and a proprietary stepped-impedance coupling structure. These design choices minimize resistive and dielectric losses, ensuring the Cavity Filter delivers maximum signal throughput for LF seismic and submarine communication links.
