50-54MHz 1.5kW Super Low Loss Bandpass Filter BPF

Intended to be used with linear amplifiers 8877, GS35, GS31, 2xGI7B and with other tubes.

6m Bad-Pass filter will easily handle any 1.5kW linear amplifier.

50-54MHz Bandpass Filter BPF uses high Q coils and capacitors with Q more than 4000. Low loss of filter achieved with careful design and adjustment.

Although intention of this filter is to be used as transmitting filter, design allows also to be used as receiving filter before wideband LNA to protect sensitive device from strong out of band signals.

This BPF will suppress any harmonic on 100 MHz, 150 MHz and more.
