“…The 28 GHz RF beamforming system can dynamically steer the antenna array’s radiation pattern through electronic means, allowing for real-time adjustments based on environmental conditions. This functionality enhances both performance and efficiency, ensuring optimal operation [ 22 , 23 , 24 , 25 ]. Moreover, the integrated transceiver module possesses the flexibility to easily adjust the frequency of both the local oscillator (LO) and intermediate frequency (IF) with minimal complexity.…”

This paper presents a 5G new radio (NR) FR2 beamforming system with an integrated transceiver module. A real-time operating module providing enhanced flexibility and capability has been proposed. The integrated RF beamforming system with an integrated transceiver module can be operated in 8Tx-8Rx mode configuration simultaneously. A series-fed structure 8 × 7 microstrip antenna array for compact size and improved directivity is employed in the RF beamforming module. The RF beamforming module incorporates a custom 28 GHz, eight-channel fully differential beamforming IC (BFIC). An eight-channel BFIC in a phased-array beamforming system offers advantages in terms of increased antenna density and improved beam steering precision. The RF beamforming module is integrated with an RF transceiver module that enables the simultaneous up-conversion and down-conversion of the baseband signal. The RF transmitter module consists of a transmitter, a receiver, a signal generator, a power supply, and a control unit. The RF beamforming system can scan horizontally from −50° to +50° with a step of 10°. To achieve an optimized beam pattern, a calibration was conducted. The transmit and receive conversion gain of around 20 dB is achieved with the transceiver module. To verify the communication performance of the manufactured integrated RF beamforming system, a real-time wireless video transmission/reception test was performed at a frequency of 28 GHz, and the video file was transmitted smoothly in real time without interruption within a range of ±50°.

“…In [9] we have addressed the cryogenic characterization at 2K of the proposed compact switch as a key circuit, i.e., a "qubit size" switch, toward the implementation of monolithic quantum processors. In this paper we present all the features of the proposed compact switch and its complete experimental characterization at room temperature (300 K) for more general purposes in microwave and mm-wave communication and sensing applications [10,11], such as radars [12,13], radiometers [14] and 5G/6G mobile broadband phased-array transceivers [15,16]. The paper is organized as follows.…”

This brief reports a compact DC-110GHz single-pole single-throw (SPST) switch in 22nm FDSOI CMOS technology. The switch adopts solely three n-MOSFETs, two of them with a special device option to reduce the substrate parasitic effects, and a third n-MOSFET in parallel to the gate resistance of the series n-MOSFET to improve isolation. Unlike prior wideband mmwave switches, it does not make use of any large passive components, such as spiral inductors, transformers and transmission lines, which are prone to large parasitic effects, including losses, and require large area on silicon. Altogether, the novel switch circuit allows a very compact design, low losses and high isolation performance. The switch exhibits an insertion loss lower than 3.1 dB, an isolation better than 22 dB, and a return loss better than 12 dB, over the entire frequency range from DC to 110 GHz. The area on die amounts to 160 µm 2 , that is up two or more orders of magnitude smaller than prior wideband mm-wave SPST switches.

“…The development of mobile devices and the need for high-speed communication have resulted in considerable research on receivers operating in the mm-wave frequency bands [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In [2][3][4], the beamforming receivers were implemented by combining four channels [2,3] and eight channels [4], respectively.…”

“…However, such a high IF frequency would require additional down-conversion to the baseband, and the first down-conversion mixer may suffer from compression or self-mixing due to the LO frequency interference. In [14,15], a high IMRR was achieved in the low-IF band by using a Hartley-structured receiver with a quadrature generator that minimized the I-Q mismatch. However, these studies did not include an LO circuit integrated in the receiver, so additional VCO and frequency dividers were required for phase-locked LO generation.…”

This paper presents a Q-band image-rejection receiver using a 65 nm CMOS technology. For a high image-rejection ratio (IMRR), the Q-band receiver employs the Hartley architecture which consists of a Q-band low-noise amplifier, two down-conversion mixers, a 90° hybrid coupler, and two IF baluns. In addition, a Q-band fundamental voltage-controlled oscillator (VCO) and a frequency divider chain divided by 256 are integrated into the receiver for LO. A charge injection technique is employed in the mixers to reduce the DC power while maintaining a high conversion gain and linearity. The VCO adopts a cross-coupled topology to secure stable oscillation with high output power in the Q-band. The frequency divider chain is composed of an injection-locked frequency divider (ILFD) and a multi-stage current-mode logic (CML) divider to achieve a high division ratio of 256, which facilitates the LO signal locking to an external phase-locked loop. An inductive peaking is employed in the ILFD to widen the locking range. The Q-band image-rejection receiver exhibits a peak conversion gain of 16.4 dB at 43 GHz. The IMRR is no less than 35.6 dBc at the IF frequencies from 1.5 to 5 GHz.
