  • Mixer for a receiver
    Patent number: 6317590
    Abstract: A sub-harmonically pumped mixer has an anti-parallel diode pair switchable at twice the local oscillator frequency. Preferably, there are provided dual anti-parallel diode pairs. The local oscillator is coupled to the diode pairs by means of an unbalanced to balanced transformer. The balanced output of the transformer is coupled to the diodes and provides anti-phased signals to respective ones of anti-parallel diode pairs.
