“…This conclusion is for GFETs exploiting the inherent electronhole symmetry present in graphene. It does not preclude the possibility of higher conversion efficiency for GFETs operating in a more conventional transistor mode where frequency multiplication can arise from general input or output non-linearities, 18,19 which is beyond the scope of the current work.…”

The reflector is composed of a transmission line with electrical angle The open-end stubs provide short-circuit terminations for odd and 4th harmonic frequencies [9]. With proper values of and , the odd and 4th harmonic signal is reflected to the transistor by the reflectors to improve the 2nd harmonic CG [3].…”

An 85 to 110 GHz high efficiency, high output power frequency doubler is presented in this letter. The traveling-wave topology is used to generate even harmonics and suppress odd harmonics effectively. The output fundamental and 4th harmonic reflectors are applied to enhance the efficiency, conversion gain and fundamental rejection. The measured results show a peak conversion gain of 3.2 dB and peak efficiency of 11.2% with a saturated output power of 9 dBm at 100 GHz. The doubler exhibits higher than 30 dB fundamental rejection from 85 to 110 GHz with a compact chip size of 1.5 0.9 mm .Index Terms-Frequency doubler, high efficiency, high output power, reflectors, traveling-wave.

“…Until recently, many kinds of passive multipliers using diodes were the dominant components developed for use at millimeter-wave frequencies [2,3]. In general, active frequency multipliers are preferred because they offer lower conversion loss (or even conversion gain), wider bandwidth, and better isolation [4,5].…”

An active frequency doubler monolithic microwave integrated circuit (MMIC) for E-band transceiver applications is presented in this letter. This MMIC has been fabricated in a commercial 0.1-μm GaAs pseudomorphic high electron mobility transistor (pHEMT) process on a 2-mil thick substrate wafer. The fabricated MMIC chip has been measured to have a high output power performance of over 13 dBm with a high fundamental leakage suppression of more than 38 dBc in the frequency range of 71 to 86 GHz under an input signal condition of 10 dBm. A microstrip coupled line is used at the output circuit of the doubler section to implement impedance matching and simultaneously enhance the fundamental leakage suppression. The fabricated chip is has a size of 2.5 mm × 1.2 mm.
