50MHz 1.5kW 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.

On picture is 50-51MHz filter for reference only. This one is wideband 50-54 MHz. 

Here are presented measured results with HP8753ES network analyzer full two port calibrated.

Achieved results on a built Bandpass filter:

1.8MHz=-65 dB
3.8MHz=-57 dB
7 MHz = -39 dB
14 MHz = -11dB
21MHz=-5dB
28 MHz = -4 dB
50 MHz = -0.13 dB
52 MHz = -0.13 dB
54 MHz = -0.13 dB
88 MHz=-22dB
100 MHz = -44 dB
108 MHz = -44 dB
144 MHz = -42 dB
150 MHz = -43 dB
162 MHz = -44 dB
432 MHz = -48 dB
 
 
1k5 and 4kW filters share same high quality components except connectors, fan, and different design of aluminum box.
