“…5(b) shows the phase difference of and signals as a function of oscillation frequency. Although the measured frequency range was limited due to the lossy switch and measurement setup, the quadrature oscillation was well demonstrated with resulting I/Q phase imbalance less than at around 325 GHz (see Table I) [11], [12].…”

We present a 325 GHz quadrature voltage controlled oscillator (QVCO) using 0.25 InP HBT technology and superharmonic coupling of two differential Colpitts VCOs. The individual VCOs exhibit about single-ended output power and 10 GHz frequency tuning range. The quadrature oscillation is successfully demonstrated with dc power consumption of 92.4 mW and phase imbalance less than at around 325 GHz. Index Terms-InP HBT MMIC, quadrature voltage controlled oscillator (QVCO), 300 GHz, THz wireless communication.

“…One way to extend the output frequency range is to use push-push oscillators. However, as the frequency approaches , the output power from a push-push oscillator is usually low, as reported in [1], [2]. The output power can be improved through a tuning network at the output, but only for a narrow bandwidth [3].…”

This letter presents a signal generation circuit that combines a wide tuning range voltage controlled oscillator (VCO) and a frequency doubler. The VCO provides two differential outputs with different power levels. A push-push frequency doubler is designed and cascaded to the high power output of the VCO, while the low power output is reserved to drive a frequency divider in a PLL. The VCO can be tuned from 33 to 43 GHz, with around 0 dBm output power at the low power output. Simultaneously, signal generation from 66 to 86 GHz is achieved at the doubler output, with a maximum output power of 1.1 dBm at 74 GHz ( 2.5 dBm at 81 GHz). The measured phase noise at the VCO output and the doubler output are 91 dBc/Hz and 83 dBc/Hz at 1 MHz offset ( 112 dBc/Hz and 106 dBc/Hz at 10 MHz offset), respectively. The circuit is realized in a 0.8 m SiGe heterojunction bipolar transistor process, with f T f max of 80/90 GHz. The VCO consumes 81 mA current while the doubler consumes an extra 17 mA from a 4 V supply. The circuit demonstrates the possibility of wide-band signal generation up to f max with sufficient output power (e.g. to drive a mixer) in a conservatively scaled, low-cost process.
