Abstract :
In this paper, an InGaP/GaAs HBT Broadband MMIC Mixer with high output power is designed within a total chip area of 1.3 x 1.0 mm2. The down-conversion mixer shows return loss of -10 dB and a conversion gain of +2.6 dB in the broadband frequency range of 400 MHz to 8 GHz. It also shows a third-order input intercept point (IIP3) of+ 16.78 dBm, a third- order output intercept point (OIP3) of +19.38 dBm, and an output-referred 1-dB compression point (PldB,out) of+10 dBm. The LO-RF leakage is -84dBm and LO-IF is -60 dBm, respectively.
