Abstract :
An X-Band balanced mixer using evanescent-mode circuitry has been developed utilising a waveguide magic-T. It shows an available conversion loss of 4.4 dB and a noise figure of 5.6 dB including a 1.2 dB noise contribution from an i.f. amplifier at a radio frequency of 8.61 GHz. Image and sum frequency are largely independently tunable.
