“…Because of the frequency range of more than 100 GHz, a passive balun, like a rat-race coupler, would have significant losses because of the limited bandwidth of these coupler structures. We used two frequency doublers fed with quadrature signals to generate a differential output signal [66], [67], [68]. These quadrature signals are generated by integrated hybrid couplers described in Section III-C1.…”

Commercial frequency-modulated continuous-wave (FMCW) radar systems are well-established in the frequency range up to 100 GHz, with some exceptions operating in the D-band and above. There are multiple advantages of operating at higher frequencies, such as the use of ON-chip antennas and, therefore, the omission of high-frequency substrates for frontend designs, which enables the fabrication of low-cost FR4 radar frontends. This work features a 360 GHz fully integrated signal source and breakout circuits at 90 and 180 GHz, manufactured in the 90 nm B12HFC SiGe:C BiCMOS technology. We present a 90-GHz wideband Colpitts-Clapp VCO combined with a static frequency divider for stabilization purposes, achieving a tuning range (TR) of 24.1 GHz and an output power of up to 6.43 dBm. Adding a frequency-doubling and amplification stage expands this circuit, achieving 51.7-GHz TR and up to 3.8-dBm output power. The 360 GHz signal source adds another frequency-doubling stage consisting of a wideband differential hybrid coupler for quadrature signal generation, amplifier chains, and two push-push frequency doublers, generating a pseudodifferential output signal with up to −1.8 dBm output power and a frequency TR of 106.7 GHz (29.9%).

“…Different architectures have been proposed in the literature to implement frequency quadruplers, frequency doublers have been either cascaded [4] or stacked in order to reduce the power consumption by reusing the bias current [9]. The latter solution, although has a low power consumption and larger bandwidth because of the less number of stages, it suffers from low output power due to the limited output power from the input push-push doublers which subsequently does not saturate the second switching quad.…”

This work presents a fully differential wideband and low power 240 GHz multiplier-by-8 chain, manufactured in IHP's 130 nm SiGe:C BiCMOS technology with fT/fmax = 300/500 GHz. A single ended 30 GHz input signal is multiplied by 8 using Gilbert cell-based quadrupler and doubler, and then amplified with a wideband differential 3-stage cascode amplifier. To achieve wide bandwidth and optimize for power consumption, the power budget has been designed in order to operate the frequency multipliers and the output amplifier in saturation. With this architecture the presented circuit achieves a 3 dB bandwidth of 40 GHz, meaning a relative 3 dB bandwidth of 17%, and a peak saturated output power of 0 dBm. Harmonic rejections better than 25 dB were measured for the 5th, 6th, and 7th harmonics. It dissipates 255 mW from 3 V supply which results in drain efficiency of 0.4%, while occupying 1.2 mm2. With these characteristics the presented circuit suits very well as a frequency multiplier chain for driving balanced mixers in 240 GHz transceivers for radar, communication, and sensing applications.
