Crystal am filters
WebThis AM crystal set is built around a Junction Field Effect Transistor (JFET) and when coupled with a separate antenna tuner performs a good bit like a Hi-Z DX set. Hi-Z sets generally make use of Litz coils, HI-Z diode, matching transformer, and … WebCohn Filter. A 4-pole crystal filter using 9MHz crystals was created using the architecture below. The crystal parameters were determined using the G3UUR method. With these parameters, I used AADE filter design software to create a Cohn Filter for my AM filter. The terminating impedance of the filter is ~338 Ω with all capacitors being 52pF.

WebAll AM/SSB rigs use a multipole crystal filter, which is switched to operate on both RX and TX. This filter is the large metal can about 2" x 1" that you see on the main chassis. For RX, it provides basic IF selectivity. For the SSB TX mode, it filters out one of the two sidebands. The second filter (if present) is a simple monolithic device ...
