50 – 54 MHz 4000 W Super Low Loss Bandpass Filter BPF for 6 Meter band.

Intended to be used with linear amplifiers 8877, GS35, GS31, 2xGI7B, and with other tubes. 6-meter Bad-Pass filter will easily handle any up to 4000 W linear amplifier.

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

Although the intention of this filter is to be used as a transmitting filter, the design allows also it to be used as a receiving filter before wideband LNA with PGA-103+ to protect sensitive devices from strong out-of-band signals.

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