6 Meters Low Loss Band-Pass Filter 4 kW, 50 - 54 MHz

  • 6 Meters Low Loss Band-Pass Filter 4 kW, 50 - 54 MHz

50 - 54 MHz 4 kW 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 Q more than 4000. Low loss of filter is 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 with SPF-5122Z or wideband LNA with PGA-103+ to protect sensitive device from strong out of band signals.

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