“…To generate mm-wave channels at 60 GHz band, we beat channel #1 and channel #2 with a wavelength λ j generated by a laser at RAU 2i and spaced by 50 GHz from wavelength λ 2i and to obtain channel #3 and channel #4, we beat the arriving wavelength at RAU 2i+1 with a wavelength λ k spaced by 60 GHz from λ 2i+1 . The mm-wave signals obtained at the output of the photodetector undergo a band-pass filter (57-66 GHz) to select the required mm-wave channel [40] then pass through several amplifiers to bring the mm-wave signal to the spread power (10 dBm). We owe to use a VGA that drive the power according to data modulation.…”

In this paper, we investigate a scalable Radio over Fiber (RoF) system compliant to 5G fronthauling requirements. The proposed RoF architecture is able to adjust the network resources and capacities to satisfy user demands in terms of service, data rate and bandwidth. The flexibility and the reconfigurability of the proposed topology are provided through the inclusion of flexible network nodes which are at the Central Office (CO), the Remote Node (RN) and the Remote Access Unit (RAU). The centralized management of the RoF system based on a Software Defined Networking (SDN) enables the monitoring of the overhaul RoF system and the reconfiguration of network nodes parameters. The proposed RoF system architecture is designed to support multi-standard operation and mm-wave services. We investigated multi-service operation assuming high speed mm-wave service at 60 GHz besides to conventional wireless services such as WiFi and WiMax. The introduced system is able to operate for different RF bands (2.4, 5.2 and 60 GHz) with various modulation schemas such as BPSK, QPSK, 16QAM and 64QAM, that may be associated to Orthogonal Frequency-Division Multiplexing (OFDM) and multidata rates up to 5 Gbps. To validate the RoF system performances, we have considered the Error Vector Magnitude (EVM) and service constellation as figures of merit at the End User (EU). The simulated results testify the architecture viability.

“…However, the cost and size of the system are important criteria for the design of such systems. Band‐pass filters are one of the key passive components in radio system and are used to ensure regulatory spectrum compliance. To meet the demand of low cost, compact transceivers, system integration technology such as system‐in‐a‐package (SiP) using integrated passive devices (IPD) technology is very well suited for millimeter‐wave radio front‐ends.…”

The NF remains less than 4.6 dB when V ctrl is lower than 1.8 V. The minimum NF of 3.7 dB is obtained with V ctrl 5 0 V at 9.2 GHz. Finally, Table 2 summarizes previously reported CMOS VGAs for comparison. Compared to other advanced CMOS technologies, this work demonstrates the lowest average NF, high peak gain while maintains good gain control range with low power consumption. CONCLUSIONIn this letter, a novel X-band low-noise amplifier (LNA) with variable gain was designed, implemented, and verified in a standard 0.18-lm CMOS. The first stage of the LNA is a CS amplifier for noise reduction, and the second stage is a cascode amplifier which incorporates a reflection-type attenuator and a parallel inductor for gain enhancement and variation. The design concept and principle are also detailed. Based on this topology, the attenuator provides 9.3 dB of gain variation with good return losses, and the NF of the LNA ranges between 3.7 and 4.6 dB in all modes. Good agreement between the simulated and measured results establishes the practicality and usefulness of the design methodology, and the VGA reveals great potentials for system-on-chip integrations especially for X-band radar or other wireless communication applications.ABSTRACT: This article presents a design approach of a band-pass filter which is fabricated on an integrated passive device process and is capable of operating over the unlicensed 60-GHz band (57-64 GHz). The band-pass filter proposed in this article evolves from a typical one comprising two identical, mirrored open-loop half-wavelength microstrip line resonators. The experimental results demonstrate an insertion loss of less than 2.4 dB, a return loss of better than 10 dB over the 60-GHz band, and a 3-dB bandwidth of 24 GHz ($42%). The simulation and measurement results are well matched up to 110 GHz. This filter is suited for system-in-a-package V-band front-end systems.

“…For wireless communication applications, a bandpass filter is a crucial and mass-used component to allow signals and to suppress noises in the specific frequencies [5], and so far, it remains a challenge to realize a suitable bandpass filter for the 60 GHz technique to satisfy the demanding requirements of sharp bandedge transition [6][7][8][9], highratio bandwidth, and excellent transmittance efficiency [6,7]. Here, we introduce a new class of metamaterials to demonstrate right-handed response from its cavity modes and left-handed response from its plasmonic resonance simultaneously, leading the collective two-handed response to constructing a high-ratio bandwidth (HRB) bandpass filter [10].…”

Abstract-By enabling both cavity modes and plasmonic resonance together in the designed two-handed metamaterial, we demonstrate a square-wave-like (SWL) bandpass filter with high-ratio bandwidth (HRB). Our results show that this metamaterial-based bandpass filter possesses high-ratio bandwidth of 30 GHz centered at 92 GHz, excellent transmittance beyond 87.5%, sharp transition within 1.0 GHz from −3 dB to −20 dB as upper and lower band edge transitions, and dualband behavior. Such an HRBSWL bandpass filter can be scalable and readily applicable for the commercialized unlicensed 60 GHz spectra with a bandwidth exceeding 7 GHz, solving the challenge of conventional passive bandpass filters to allow wide bandwidths and great quality factors simultaneously.
