A 135GHz single-ended mixer in 0.13μm SiGe HBT for high-speed demodulation

This paper presents a millimeter-wave (mmWave) mixer in 0.13μm SiGe HBT technology. The single-ended mixer is designed to down convert modulated mmWave signals with high speed up to 10Gbps. The on-wafer measured results show that, the fabricated 0.7mm × 0.5mm mixer exhibits a 10dB return-loss bandwidth covering the whole D-band (110-170GHz) at RF input port.
