“…A number of active mixers have been reported so far in various topologies and processes for different applications. SiGe-based heterojunction bipolar transistor (HBT) mixers [1,2], SiGe-based BiCMOS mixers [3,4,5,6,7], CMOS-based mixers [8,9,10,11] and mixers based on InP HBT technology [12,13,14,15] were presented. Particularly, InP double heterojunction bipolar transistor (DHBT) has the advantages of outstanding high frequency performance, high electron mobility and high breakdown voltage [16,17], which indicates that InP DHBT is an attractive choice for wideband mixers.…”

This letter presents a wideband and high conversion gain mixer based on Gilbert-cell in InP DHBT process. Capacitive degeneration is introduced to increase the bandwidth of the mixer with no voltage drop and few cost of area. Current bleeding technique is employed to improve conversion gain. Utilization of device f t is analyzed to achieve 0.919. The measurement demonstrates a conversion gain of 14.5 dB at 26 GHz with -3 dB bandwidth of 49 GHz. BW/ f t of 0.306 and GBP of 260 GHz are obtained, which are believed to be among the best compared to mixers fabricated with the same size process.

“…Gilbert topology is well known for providing high CG, good port isolation. [49][50][51][52][53] Adiseno et al proposed a Gilbert mixer with flat CG, but the design suffers from high NF and low IIP3. 54 Although the design is suitable for compact, low IF receivers, the overall power consumption is high.…”

The implementation of software-defined radio necessitates a versatile radio frequency (RF) front-end that can support multiple standards in different frequency bands. This article presents the state-of-the-art multiband and wideband mixers in the context of different receiver architectures suitable for softwaredefined radio (SDR). Wideband and multiband mixer designs reported in the literature are categorized on the basis of their circuit architecture. This study tabulates the results of mixer designs with an emphasis on noise figure (NF), conversion gain (CG), linearity, and image rejection ratio. The best parameters reported in the comparison are 68-84 dB of CG, 3.2 dB of NF, 2.5 mW of power consumption, 12.5 dBm of third-order input intercept point, and 0.015 mm 2 of area at different frequencies. The study also discusses the design challenges and techniques to overcome those issues. The article concludes with the summary and prospective developments for SDR architectures.

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)
