Description

6 Meters Low Loss Band-Pass Filter 1.5 kW, 50 - 54 MHz

Intended to be used with linear amplifiers 8877, GS35, GS31, 2xGI7B and with other tubes. 6 meter Bad-Pass filter will easily handle any 1500 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 to protect sensitive device from strong out of band signals.

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

The recorded data on the assembled filter with HP8753ES network analyzer full 2-port calibrated are presented below.

Additional Measurements for 6 Meter 1.5 kW Band-pass filter:

1. Zoomed measured data of 50 - 54 MHz transmitting band-pass filter. Insertion loss - S21 (Attenuation) is set to 0.2 dB per division! The same attenuation can be seen at every band point, as well as super high adaptation.
