“…Although differential solutions are often used for beamformer chips, LNAs are typically implemented singleended since antennas are often implemented single-ended. Having at least the first stage single-ended helps to achieve low NF, avoiding the first block in the chain to be a balun [26], [27]. Hence, our proposed schematic is a single-ended LNA.…”

This article presents a compact integrated receiver front-end for phased-arrays at 5G n257/n261 band (26.5-29.5 GHz) employing both a low-noise amplifier (LNA) and a novel passive phase-shifter based on variable-phase all-pass networks. The proposed phase-shifter topology is analysed and designed using 0.25 µm BiCMOS achieving continuous tuning capabilities with 360 • phase range over a 25-33 GHz frequency range under 0.1 mm 2 of area. The proposed phase-shifter is measured standalone, achieving 8.3 ± 0.55 dB losses at 29 GHz with an RMS gain error below 0.6 dB across the entire frequency range. When quantizing the continuous phase-shift into 6 bits, an RMS phase error < 3 • is obtained. To build the LNA-Phase-shifter combo, the phase-shifter is then integrated with an LNA optimized for compactness, which was measured standalone, showing a noise figure below 3.2 dB across the n257/n261 band and 20 dB gain under 0.0625 mm 2 of area. The small size of both the phase-shifter and LNA enables an ultra-compact phasedarray receiver front-end under 0.2 mm 2 of area. The front-end is measured, achieving 11.5 ± 0.53 dB of gain, RMS gain error below 0.42 dB and RMS phase error below 3.2 • over the entire n257 band, measured input-referred P1dB of -25 dBm and a 15 mW DC power consumption.

“…There are several 5G NR transceiver architecture options for user equipment such as RF, baseband (BB), and intermediate frequency (IF) interfaces [1]- [10]. The IF interface is the most realistic choice and widely employed in mobile platforms owing to the lower loss and ease of matching at the IF signal frequency [1], [3], [4], [6]- [9]. One chip solution, including 5G NR sub-6 GHz frequency range 1 (FR1) and mmWave IF transceiver, can also be used to implement low-cost and highly integrated IF interface option [4].…”

In this paper, a 24-40 GHz broadband millimeter-wave (mmWave) down-conversion doublebalanced mixer with a dual-band local oscillator (LO) buffer employing RF and IF coupled resonators is presented for 5G new radio (NR) frequency range 2 (FR2) cellular applications. The proposed mixer comprises a transformer-coupled gm-boosted common-gate (CG) Gm-stage, a single-to-differential currentto-current RF capacitor-tuned coupled resonator, active switching stages with dual-band three-stage LO buffers, a current-to-voltage IF coupled resonator with gain equalization, and a wideband IF buffer with a transformer-based balun. The transformer-coupled gm-boosted CG Gm-stage improves the NF and provides broadband input power matching. RF and IF coupled resonators enable an RF operating frequency range of 24-40 GHz and IF 1 dB bandwidth of more than 0.8 GHz, respectively. The implemented mixer was fabricated using a 40 nm CMOS process and characterized primarily in the 5G NR FR2 bands. The active die area was 0.654 mm 2 , and the mixer drew a bias current of 16 mA from a nominal supply voltage of 1.1 V. The mixer exhibited an RF operating frequency range of 24-40 GHz, noise figure of 12.4 dB, conversion gain of 1.2 dB, IF 1 dB bandwidth of 1.1 GHz, and output-referred third-order intercept point of 6.8 dBm.INDEX TERMS 5G, broadband, capacitor-tuned, cellular, coupled resonator, frequency range 2 (FR2), down-conversion mixer, dual-band, gain equalization, gm-boosted, LO buffer, millimeter-wave (mmWave), new radio (NR)
