75MHz 7th order Chebychev Low Pass filter designed to to suit our Mitsubishi Module Kits, but can also be used with other Amplifiers. The filter has been specifically designed to suit the RA30H0608M module for the 70MHz 4M band. The Mitsubishi RA30H0608M modules require the use of a suitable Low Pass Filter to reduce the -25dBc second harmonic to a suitable level that complies with current ACMA and FCC rules of at least -50dBc. The Chebychev filter has been designed for low ripple,and uses low loss RF capacitors,high Q inductors to reduce RF losses. It will easily handle 100W carrier, and has at least -45db loss at the second harmonic of around 144MHz.
