I have put details of Version 2 of my Pre-Filter on http://homepages.nildram.co.uk/~baker/
This version has a resistive pad as input termination to improve the IMD performance of the Post-Mixer Amplifier. The 5dB loss in the pad is made good with a JFET amplifier on the filter output. 73 Stewart G3RXQ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
