Crystal am filters
WebThe CW filter is common and fairly inexpensive, it was used in all of the SB-300 series receivers along with the SB and HW series 5 band transceivers. The AM filter tends to command a higher price and is more difficult to find. Heathkit made the AM filter in 3.75 and 5.00 Khz. bandwidths, the 3.75 was typically installed in the SB-300/301/303 ... 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.
