“…The line offers attenuation and characteristic impedance between those of microstrip and coplanar, plus the a ground plane conductor close to the silicon surface where the transistor terminals are available. This is useful to reduce the parasitic to ground of the common terminal of the device [21], [22]. Two line designs ensured a compact layout.…”

This work presents a direct-conversion receiver for G-band applications formed by a cascaded single-stage distributed amplifier optimized for low noise, a single-balanced active mixer with inductive peaking and broadband RF matching, and a local oscillator (LO) driver. The receiver is optimized for reduced DC and LO power consumption, while practical levels of linearity and noise are retained. Prototypes of the complete receiver and of the stand-alone mixer are implemented in 0.62 mm 2 and 0.39 mm 2 of a 130 nm SiGe BiCMOS technology with 450 GHz maximum-oscillation frequency. The measured receiver saturated gain in LO compression is 17 dB with a 6 dB band of 60 GHz and a 3 dB band of 30 GHz, while the input power which compresses the gain by 1 dB (P in1dB ) is −35 dBm. The simulated receiver double-sideband noise figure is 11 dB. Finally, the circuit requires an LO power of −17 dBm at 170 GHz and a DC power of 98 mW. The measured gain of the mixer is −13 dB with a 3 dB band of 70 GHz. The component P in1dB is −20 dBm for −18 dBm LO power and 53 mW DC power. These circuits offer one of the largest operation bandwidth together with one of the lowest DC and LO power consumption against the state of the art.
