160m High power BPF – 4Kw

230,00 VAT not included

This is a High power (4Kw) 160m Band Pass Filter for Big Guns.

Once, you have band pass filter after linear amplifier, well designed and reliable, you will forget about all the problems with interferences between the bands and strong harmonics.

All BPF’s are hand made

This bandpass filter is specificly projected for 1.8 MHz to 2 MHz frequency range that can withstand 4kW linear amplifier. This filter is projected for all international 160m frequencies ITU Region 1 1.810MHz-1850MHz, ITU Region 2 1800MHz-2000MHz and ITU Region 3 1800MHz-2000MHz.

High power 4kW filter works from 1.8MHz to 2MHz.

Its external appearance is shown in the following figure:

Once you have well designed and reliable band pass filter after linear amplifier, you will forget about all the problems with interferences between the bands and strong harmonics.

Insertion loss of main (1st) harmonic is less then 0.12dB and it is from 1.8Mhz up to 2MHz, second harmonic is suppressed by more then 40dB! Images from the network analyzer are shown in the next section. All measurements on assembled filter were done with HP8753ES full 2-port calibration. This graph represents insertion loss – S21 from 1 MHz to 4 MHz.
