“…Such inphase noise is generated from the source noise of M 1 , which is amplified by the auxiliary path before canceling. By properly adjusting the gains of M 3 and M 4 , the noise-canceling ratio is improved [48]. In the proposed NCLNA, the gain and operation bandwidth is determined by the performance of the main path.…”

This article presents a 23-40-GHz phased-array receiver (RX) capable of reconfiguring to achieve fine phase step and high gain range. Such phased-array RX consists of a 14-bit phase-gain manager and a wideband noise-canceling low-noise amplifier (NCLNA). The proposed phase-gain manager includes two 7-bit variable gain amplifiers (VGAs) in radio-frequency (RF) domain, two pairs of mixers, and two variable gain signmap (VGSM) circuits in intermediate-frequency (IF) domain. The proposed phased-array RX can not only provide a maximum 14-bit phase-tuning operation and >35-dB gain variation range but also achieve an improved calibration-free image rejection ratio (IRR) by introducing the dual-mode image rejection operation. Based on the aforementioned structure, a four-element phased-array RX is implemented and fabricated in a 40-nm CMOS technology. The whole circuit size is 2.2 × 1.3 mm, while consuming 52 mW per element. The measured result shows a state-of-the-art minimal noise figure (NF) of 3.8 dB, which supports 3 Gb/s, 64-QAM and 2.4 Gb/s, 256-QAM modulation signal.

“…The models in Section 4.3 are now used to develop a measure of link rate coverage for OtI scenarios with "traditional" or Low-e glass. Table 5 defines typical parameters for the 28 GHz BS and UE representative of recent advances in state-of-the art mmWave hardware [43][44][45][46][47]. We select conservative values for these parameters to reduce the possibility of overestimating data rates, and we include an additional 5 dB of losses in 𝑁 𝐹 .…”

Outdoor-to-indoor (OtI) signal propagation further challenges the already tight link budgets at millimeter-wave (mmWave). To gain insight into OtI mmWave scenarios at 28 GHz, we conducted an extensive measurement campaign consisting of over 2,200 link measurements. In total, 43 OtI scenarios were measured in West Harlem, New York City, covering seven highly diverse buildings. The measured OtI path gain can vary by up to 40 dB for a given link distance, and the empirical path gain model for all data shows an average of 30 dB excess loss over free space at distances beyond 50 m, with an RMS fitting error of 11.7 dB. The type of glass is found to be the single dominant feature for OtI loss, with 20 dB observed difference between empirical path gain models for scenarios with low-loss and high-loss glass. The presence of scaffolding, tree foliage, or elevated subway tracks, as well as difference in floor height are each found to have an impact between 5-10 dB. We show that for urban buildings with high-loss glass, OtI coverage can support 500 Mbps for 90% of indoor user equipment (UEs) with a base station (BS) antenna placed up to 49 m away. For buildings with low-loss glass, such as our case study covering multiple classrooms of a public school, data rates over 2.5/1.2 Gbps are possible from a BS 68/175 m away from the school building, when a line-of-sight path is available. We expect these results to be useful for the deployment of mmWave networks in dense urban environments as well as the development of relevant scheduling and beam management algorithms.

“…Benefit from the advantages of high integration and relatively low cost of CMOS technology, several mmwave LNAs in the CMOS process have been reported [1,2,3,4,5,6,7]. However, due to the lossy silicon substrate and low carrier mobility, these LNAs have relatively poor noise figure, gain, and linearity performance.…”

This letter presents a 28-38 GHz low-noise-amplifier (LNA) monolithic microwave integrated circuit (MMIC) using 0.15 µm GaAs pseudomorphic high electron mobility transistor (pHEMT) process. Inductive degeneration and shunt-series peaking techniques are employed to obtain simultaneous input and noise matching (SINM) and wideband flat gain. A novel wideband multistage noise matching technique based on a high-pass matching network is proposed to achieve low NF and further improve gain flatness over a wide frequency range. A four-stage LNA prototype is designed and fabricated based on the proposed technique. Measurement results show that the proposed LNA has a 1.6-dB minimum NF and an average gain of 23.7 dB in the entire operating band. S11 and S22 are better than −10 dB from 30 to 37 GHz. The measured output 1-dB compression point (OP 1d B ) is higher than 14.8 dBm from 28 to 38 GHz. The chip is realized within 2.1*1.5 mm 2 and consumes 56 mA current from a 5 V supply.
