432MHz -0.06dB 2.5 kW Bandpass Filter

430 - 440 MHz 2500W -0.06 dB Transmitting - Receiving Band-pass Filter with 7/16 DIN connectors

Filter is completely the same as 1000 W version except connectors (7/16DIN - "N").

With its extreme low insertion loss this filter could be used as transmitting and / or receiving filter in line with antenna.

- As transmitting to suppress any harmonics from 70cm up to 1kW linear amplifiers.
- On receive side before LNA to protect receive performance from any HF, FM 2m, 220 MHz or 23cm strong stations.

Measure data on the assembled filter with HP8753ES network analyzer full 2-port calibrated.
