In this paper, the study of a design and fabrication of the receiver MMIC mixer for L-band application is described. The mixer is composed of active LO and RF balun to integrate on a chip and applied a newly proposed bias circuit to compensate the process variations of active devices. The conversion gain of the mixer is -14 dB, IIP3 is approximately 4 dBm and port-to-port isolation is over 25 dB. The newly proposed bias circuit is composed of a few FETs and resistors, and can compensate the variation of the threshold voltage by the process variations, temperature changes and etc. The designed chip size is $1.4\;mm{\times}1.4\;mm$.
