“…Fig. 2 shows the relationship between the data rate and transmission distance in wireless communications [2,5,6,7,8,9,10,11,12,13]. One way to increase the data rate is to increase the carrier frequency of wireless communications systems, and we have been developing 120-GHz-band wireless link system for this purpose [14,15,16].…”

This paper describes millimeter-wave (MMW) system technologies for wireless communications, imaging, and sensing. MMW systems have advantages of large bandwidth and short wavelength, and recent progress in electronic and photonic device enables us to handle MMW signals easily at low cost. State-of-the-art MMW wireless communications systems can transmit over-10-Gbit/s data, and research on transmission characteristics is progressing steadily. MMW imaging systems using nearfield dispersion can achieve high resolution, and they are starting to be used for non-destructive inspections of infrastructure. An MMW sensing system based on photonic technologies enable us to cover large bandwidths and is now being investigated for remote sensing of gasses in the fields of radio astronomy and disaster prevention.

“…It has been recently considered for wired backplane channels [2], [3], but large guard bands are used to avoid inter-band interference. Analog multiband techniques have also been considered for an indoor 60 GHz channel [4], but a guard band is implicitly provided by stacking the subbands next to each other after accounting for excess bandwidth, and channel dispersion was not addressed. The application of analog multiband to outdoor 60 GHz channels was considered in [5] (the approach was termed analog multitone in that paper).…”

Abstract-We propose an approach to scaling communication bandwidths over dispersive channels that preserves the advantage of DSP-centric receiver design, while sidestepping the difficulty of scaling analog-to-digital conversion (ADC) to higher and higher bandwidths. This is accomplished by channelizing the available bandwidth into contiguous subbands in the analog domain, with the width of a subband chosen so that digitization is possible at reasonable cost and power using existing ADC technology. We illustrate these ideas for multiGigabit indoor mmwave communication, with GHz bandwidth divided into subbands of width 250-500 MHz. The channel delay spread even after beamforming can be as large as 20 ns, hence the channel seen within subbands is dispersive. Further, the contiguity of subbands and the sloppy analog channelization implies that adjacent subbands interfere with each other. We show that OFDM within subbands is an attractive approach in these settings: the channel dispersion within subbands can be handled with a moderate cyclic prefix, while the inter-band interference manifests itself only on the edge subcarriers. We clarify the structure of the inter-band interference, and show that it is effectively suppressed by adaptive linear Minimum Mean Squared Error (MMSE) techniques for joint detection across adjacent subbands. Our performance evaluation is carried out using channel models developed for the IEEE 802.11ad 60 GHz standard.

“…The rapid growth in data communication and multimedia applications has been driving research on millimeter-wave frequency band high speed communication, such as 60-GHz radio system and over 100-GHz millimeter wave communication system [1][2][3][4][5][6][7]. In order to provide high enough data rate with smaller equipment size and lower price, the demand for high speed integrated circuits (ICs) operating at tens of Gbps remains unremitting.…”

Abstract-In this paper, a wide bandwidth and wide dynamic range AGC amplifier is presented. A push-pull variable gain amplifier (VGA) structure is proposed for wide dynamic rang. Moreover, the bandwidth enhancement technique is used in the post amplifier design to ensure the wide bandwidth and gain of whole circuit. The experimental results demonstrate that the proposed AGC amplifier fabricated in 0.13 µm SiGe BiCMOS process, achieves a 23-GHz bandwidth and 36-dB dynamic rang whereas the power and area consumption are 57.6 mW and 1.9 mm 2 , respectively.
