“…These results are enabled by the distributed amplifier techniques which allowed for a singleend receiver design while retaining broadband operation. In detail, the distributed approach enabled to stablish 4 dB higher conversion gain while reducing the LO power requirements by 7.5 dBm when compared to [6]. The LO power reduction is indeed beneficial when considering the difficulties in generating power at frequencies approaching 200 GHz.…”

“…For a given transistor parameters, the length of the line The mixer switching pair is formed by the transistors Q 2 , sized with an emitter area A E,x1 = 1×0.9×0.07µm 2 to sustain half Q 0 bias current each. The externally provided single-ended LO signal at 170 GHz is amplified with an LO driver, and then a three-line balun [6], [24], [25] feeds the switching pair with a differential signal. The 3D and crosssection views of the balun are presented in Fig.…”

“…Fast transfer of huge amount of data, such as an example memory-storage backup, or 3D video streaming for virtual reality are then enabled. Although the key feature to establish +100 Gbps wireless links is the use of the broad frequency bands available at sub-THz frequencies, limited research have been done to maximize the transceivers bandwidth [6]. Absolute large bandwidth of operation are in fact reached in previous works re-adapting narrow-band design techniques and up-scaling the carrier frequencies at sub-THz [3], [4], [7].…”

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.
