DOUBLE_BALANCED_MIXER_1

Uses Watkins-Johnson M6 low-level hot-carrier-diode double-balanced mixer as replacement for FET second mixer amateur-band dual-conversion receiver to reduce intermodulation distortion.U310, CP643, or CP651 can be used in place of U320 high-transconductance JFET. Pi-network output circuit couples 2000-ohm output of JFET stage to 2000-ohm IF filter. All inductance values are in microhenrys.-A. J.
