Abstract :
A multipurpose MMIC gate mixer has been designed, fabricated and measured. The mixer exhibits a maximum conversion gain of about 0 dB in the frequency range of 32 GHz-38 GHz with an intermediate frequency (IF) of 100 MHz and an IF load of 50 /spl Omega/. With an external IF matching network a conversion gain up to 5 dB can be achieved. The mixer which consists of one pseudomorphic HFET represents state of the art performance.<>
