Passive Band pass filters  for  home-made  Receivers or Transceivers 

 

Can be used as the additional band pass filter between antenna and a cheap receiver.

 

People say it pass perfect as PreSelector to PCR100, PCR1000 , SDR, Pilgrim, receivers...

 

                                                         PCB Dimension is 163x55 mm

 

 This unit tuned  for 160,80,40,30,20,17,15,12,10 m   amateurs   bands.

 

                                                                  Rin=Rout=50 Ohm.

 

Losses are 1-3 dB. It has RF amplifier with frequency compensated gain(10-20dB), using one medium power RF transistor , and attenuator -20dB.

 

The operating voltage for instaled relays is 12V (if you like you can order filter with relays wich work 9..18V) .

 

Passband ripple is abt. 0.5dB inside the band .

 

 

We offer 2 options of relay:

1. 12Volts (Working range 9..18V)

2. 24Volts (Working range 18..27V)
