“…References [32]- [34] describe MMIC circuits based on GFETs. Although they reported good conversion gain values, LO signals with frequency around 100 [33], [34] and 200 GHz [32], and power level between 8 and 16 dBm are used, requiring external high-performance frequency multipliers. On the other hand, works [8] and [42] present subharmonic mixers based on macroscopic graphene sheets, following a design approach similar to that used in this work.…”

In this work, a graphene-based single-stage high-order subharmonic mixer is presented. The device is able to up-and downconvert a signal in the 330-500 GHz frequency range, using a local oscillator signal with frequency located in the 26-40 GHz band. It exploits the strong nonlinear electromagnetic behavior exhibited by macroscopic graphene sheets when they are exposed to an incident electromagnetic wave to generate the output signal as a mixing product between the input signal and a high-order harmonic component of the local oscillator, which is internally generated without requiring additional circuitry. A prototype was implemented and its performance was experimentally characterized considering several different local oscillator multiplication orders. The maximum measured downconversion gain is around −50 dB, whereas the maximum output signal reached when working as upconverter is −43 dBm at 340 GHz and −63 dBm at 480 GHz. These values are good enough to be used in practical short-range applications. Furthermore, the measurement results are in good agreement with the theoretical predictions about graphene behavior.

“…Conventionally, depending on its drain bias, a mixing transistor can be classified exclusively as active (V ds ≠ 0) or passive (V ds = 0). While active mixing comes from the LO-induced transconductance (G m ) modulation, passive mixing relies on channel-conductance (G ds ) modulation [21][22][23][24]. In the more advanced silicon processes such as 65-or 40-nm CMOS where the early effect cannot be neglect (because of their short channel length), a strict separation of active and passive mixing becomes impossible, as both G m and G ds will be affected whenever V ds ≠ 0.…”

This manuscript presents the design of a W-band receiver in which an radio frequency-low noise amplifier (RF-LNA), a wideband mixer, intermediate frequency (IF) amplification, a local oscillator frequency (LO) tripler and a driving amplifier are all integrated into one single chip of 1050 × 820 μm 2. To effectively extend the mixer's IF bandwidth while retaining its conversion gain, impacts of the mixing transistor's drain bias and output loading impedance are explored using a dual-modulation conversion-matrix method, which allows both the LO-induced transconductance modulation and channel-conductance modulation to be considered simultaneously. It is shown that, by merging the input capacitance of the IF amplifier into a highimpedance artificial transmission line, an actively biased mixer can have constant conversion gain over broad bandwidth. A 77-110 GHz 65 nm-complementary metal-oxide-semiconductor (CMOS) receiver with 33 GHz IF bandwidth is then designed and measured. Its conversion gain and noise figure are 10 and 20 dB, respectively, and the input-referred P1 dB is −15 dBm; the overall power consumption is 330 mW under 1.3 V drain bias.

In the modern day, wireless communications systems are widely used for medical services and medical information security. A wireless communication device for medical services is required for a high performance and small size technique. In this article, a proposed compact size of the single‐ended mixer using small size of the Wilkinson power divider with T‐shaped transmission line is presented. The compact size of the mixer used for small size is based on Wilkinson power divider using T‐shaped transmission line which is connected to amplifier circuit part. The electrical length of the transmission line for the conventional Wilkinson power divider was 90°. However, the electrical length of the T‐shaped transmission line was 30°. Therefore, the physical length was reduced by 1/2 times. The size of a proposed mixer was 22.21 × 18.32 mm2 at a center frequency of 2.165 GHz. It will be applied to a transceiver for wireless communication system of medical services.
