| Abstract: | In this paper the design and performances of Ka band integrated eircuit mixer are described. The mixer uses commercially available low cost diodes. An approximate calculation method is given to solve the excitation problem of finline magic tee in this mixer, and the design empirical formulas for circuit engineering are presented. The mixer with an IF am-plifier has a DSB minimum noise figure of 4.9 dB and an isolation of greater than 20 dB. This noise figure is close to the minimum noise figure of the diodes. |
