Re: How to set up for the Demo RF kit for the 30 Mhz band pass filter reading #learning

 

The boards use three terminal ceramic filters for Bandpass. (Really only two terminal, but can be installed without regard to “polarity”.

They are actually ceramic resonators and sell for about 10-15 cents apiece from China.

Since the evaluation boards have been sold for as low as $8.00, the manufacturers will use low cost components.
