Abstract

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 to 155 GHz and is based on double balanced Gilbert mixer cells. The design is tested with a CW input signal at 1 GHz and 0 dBm LO power and exhibits up to 6 dB conversion gain and more than 22 dB image rejection ratio. The LO signal is suppressed by more than 27 dB. The chip consumes 78 mW DC power and can provide up to 3 dBm RF power in saturation. The active chip area is 560μm× 440μm.
