We present a highly integrated quasi-millimeter-wave receiver MMIC that integrates 22 circuits in a 3 × 2.3mm area using threedimensional MMIC (3D-MMIC) technology. The MMIC achieves low noise (3 dB) and high gain (41 dB) at 26 GHz by using an on-chip image reject filter. It integrates a multiply-by-eight (X8) local oscillator (LO) chain with the IF frequency of the 2.4 GHz band and can use low-cost voltagecontrolled oscillators (VCOs) and demodulators in a 2-3 GHz frequency band. Multilayer inductors contribute to the miniaturization especially in a 2-12 GHz frequency band. Furthermore, it achieves a high dynamic range by using two step attenuators with a new built-in inverter using an Nchannel depression field-effect transistor (FET). The power consumption of the MMIC is only 450mW.
