“…1. The mixer-first architecture with a fundamental LO driver can improve the conversion gain and NF of the receiver chain owing to the enhanced mixer performance under the limited RF performance (fRF>fmax/2) of the active device [22]. Alternatively, placing a low-noise amplifier (LNA) at the beginning of the receiver chain, followed by mixers, can improve the NF and obtain a higher signal-to-noise ratio (SNR), enabling higher data transmission rates [20].…”

“…To provide a differential RF signal to I and Q mixers of the mixer-first receiver (Rx1), a compact-size RF distributor using a Marchand balun followed by an RF power divider was employed [22]. The simulated insertion loss is around 2 dB while the isolation between I and Q RF ports is about 11dB at 275 GHz.…”

“…To achieve broad bandwidth performance, improved operational efficiency, and enhanced isolation between the LO and RF signals, an active double-balanced mixer structure was chosen for the frequency down-conversion mixer in the quadrature receiver. The receivers utilize a modified Gilbert-cell mixer as I and Q mixers to improve the noise figure (NF) and the conversion gain by avoiding the effects of the parasitic capacitances at the common nodes [22]. The output current of the BJT-based Gilbert cell is given by tanh tanh 2 2…”

“…During the 2019 World Radiocommunication Conference (WRC- 19), the 300 GHz band (275-296 GHz) was allocated for land mobile and fixed services. Along with the IEEE Standard 802.15.3d which defines the physical layer around 300 GHz, these allocations have significantly influenced the development of various Terahertz (THz) transceivers [3]- [14], standalone transmitters [15], [16], and receiver designs [17]- [22] within this frequency range. Wireless communication links have proposed achieving data transmission speeds of over 100 Gb/s using SiGe technology [7], [8], [9], [10], while CMOS transceivers achieved data rates of 80 Gb/s by employing double-rat race techniques to increase the operating frequency [6].…”

We report two 275-GHz quadrature receivers (Rx's) with mixer-first and LNA-first architectures in a 130-nm SiGe BiCMOS process. Both quadrature Rx's contain I and Q mixers implemented with a modified Gilbert-cell mixer with swapped RF and local oscillation (LO) ports to downconvert the RF signal at 260-290 GHz to the I and Q intermediate frequency (IF) bands at 0.1-30GHz. For a cost-effective solution, a compact 260GHz quadrature LO chain is integrated with a compact frequency tripler with an Eband driving amplifier (DA), a 260-GHz DA, and a differential hybrid coupler to generate the quadrature LO signals for I and Q mixers. Comprised of a push-push doubler cascaded with a single-balanced mixer, the frequency tripler was employed to isolate the LO harmonic leakages from the IF band. A wideband IF amplifier was used for an aimed conversion gain higher than 20 dB in each channel. In the measurement, the implemented mixer-first and LNA-first Rx's achieved a minimum single-sideband (SSB) noise figure (NF) of 22.3 and 21 dB, a peak gain of 21.4 and 27.5 dB with an IF bandwidth of 30 GHz. The amplitude and phase imbalances between the I and Q channels of the mixer-first Rx were measured around 1 dB and 4°. The fabricated mixer-firs and LNA-first chips occupy a whole area of 1.418 and 2.030 mm 2 , and consume a DC power of 434 and 490 mW, respectively.

“…We also consider that it is better to develop a core part of the I/Q mixer first to confirm its reliable operation at very high frequencies, because the I/Q mixer has a slightly complex circuit configuration [6,17,18,19]. A balanced mixer with two input ports is an ideal candidate of such a core part because it includes a 90degree hybrid circuit that can be used both for signal mixing/distribution of two input signals and 90-degree phase shift in local oscillator (LO) signals to the I and Q channels.…”

We developed a terahertz-wave balanced mixer fabricated on a SiC substrate using epi-layer-transferred InP/InGaAs Fermi-level managed barrier (FMB) diodes. The FMB diodes were monolithically integrated with waveguide couplers, a 90-degree hybrid circuit, and low-pass filters. The fabricated mixer was then assembled in a twoinput-port module with a broadband transimpedance amplifier and exhibited an intermediate frequency bandwidth of about 26 GHz with good inter-port isolations of more than 13 dB. The obtained minimum noise equivalent power was as low as 2  10 -19 W/Hz in the fundamental mixing mode at around 300 GHz for a local-oscillator power of about 400 W.
