In this paper, an InGaP/GaAs HBT MMIC broadband mixer with high output power is designed within a total chip area of 2.3 × 0.85 mm2. The down-conversion mixer shows return loss of 20 dB and a conversion gain of -2.7 dB in the broadband frequency range of 400 MHz to 10 GHz. It also shows a third-order input intercept point (IIP3) of +22.5 dBm, a third-order output intercept point (OIP3) of +19.8 dBm, and an output-referred 1-dB compression point (P1dB,out) of +10 dBm.
