This paper presents the design of a millimeter-wave wideband receiver front-end in a 0.13 μ m SiGe BiCMOS technology for phased array applications. The receiver front-end is suitable for a phased array time-division duplexing communication system where both the transmitter and the receiver share the same antenna. The monolithic microwave integrated circuit front-end comprises of quarter-wave shunt switches, a low-noise amplifier (LNA), an active phase shifter and a buffer amplifier. The quarter-wave shunt switch is designed using reverse-saturated SiGe HBTs. The transformer-based LNA utilizes a common-emitter amplifier at the first stage and a cascode amplifier at the second stage to exploit the advantages of both common-emitter and cascode topologies. The designed switch is incorporated in the input matching network of the LNA. The active phase shifter consists of variable gain amplifiers driven by a polyphase filter-based quadrature generator. The receiver front-end achieves a measured gain of 18.5 dB and a noise figure of 9 dB with a 3 dB bandwidth of 23 GHz from 56 to 79 GHz. The receiver phase can be tuned continuously from 0 to 360 . An output referred 1-dB compression point of - 7.4 dBm is achieved at 70 GHz. The receiver consumes 116 mW of DC power and occupies a core area of 1800μm×475μm.
