50 - 51 MHz 300 W Low Loss Band-pass Filter for 6 Meter Band
6 Meter 300 W Low Loss Bandpass Filter BPF
50 MHz Band-pass Filter BPF uses high Q coils and capacitors with Q more than 4000. Low loss of the filter is achieved with careful design and adjustment.
Intended to be used with linear amplifiers up to 300 W output.
Although this filter is intended to be used as a transmitting filter, its design also allows is to be used as a receiving filter. It can be used before Wide Band LNA with PGA-103+ to protect sensitive device from strong out-of-band signals.
Low Insertion loss filter is excellent to be placed before any LNA to protect the receiver from HF transmitters in DX expeditions or in multi-multi environment. This BPF will suppress any harmonic on 100 MHz, 150 MHz and more, and it will protect it from HF stations.
