This paper presents the electrical and layout design and optimization of Gilbert Cell mixer for frequency band of 935-960 MHz with LO-frequency of 915 MHz. The obtained maximum conversion gain is 22.2 dB, IM3 is -11.5 dBm, and ICP is -25.5 dBm, respectively. The design consist of generic Gilbert Cell mixer with differential RF input and IF amplifier with differential output. The technology of choice is VTT08 with bipolar junction transistors (BJT).
