ABSTRACT:
Signal processing circuitry, preferably for use in multiplying two input signals, one at RF frequency and one at baseband frequency, which includes at least a basic four branch bridge circuit having a diode connected in each branch in a generally symmetrical four branch circuit configuration using a single bias supply and including a trimming resistor in at least one branch for controlling the current through the diodes in such branch so that the characteristics of the diodes in all branches can be matched over substantially the complete range of control current values therefor.
