Could someone here shed some light on this ? I am experimenting with envelope detection at RF frequencies with SPICE. The mixer is a simple SPICE B signal source as B0 3 4 V(1)*V(2) where
1, 2 are the nodes at which the two signal sources are attached. THe mixer output is fed into a Schottky diode(1N5818, BAR42 etc.,) and a shunt capacitor is attached to the Schottky diode cathode. However, the diode input signal looks identical to the output - no envelope is detected. So, could someone suggest some Schottky diodes that might work at 100 MHz - 500 MHz range, and where could I get their SPICE device models. Thanks in advance for your help.- posted
