A 115-155 GHz quadrature up-converting MMIC mixer in InP DHBT technology

• This paper presents a millimeter-wave (mmWave)direct quadrature modulator in 0.25μm InP DHBT technology.The modulator operates over the frequency range of 115 GHz to155 GHz and is based on double balanced Gilbert mixer cells.The design is tested with a CW input signal at 1 GHz and 0 dBmLO power and exhibits up to 6 dB conversion gain and morethan 22 dB image rejection ratio. The LO signal is suppressedby more than 27 dB. The chip consumes 78 mW DC power andcan provide up to 3 dBm RF power in saturation. The activechip area is 560μm× 440μm.
