170MHz Lowpass Filter

170MHz 7th order Chebychev Low Pass filter designed to to suit our Mitsubishi Module Kits, but can also be used with other Amplifiers. The Mitsubishi RA30H1317M1 modules require the use of a suitable Low Pass Filter to reduce the -35dBc 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 200MHz.
