“…The achieved miniaturization level is already compatible with cubesat platforms and will be further improved exploiting the single-chip solution that the microelectronic industry is developing for the ground-based 5G telecommunication and imaging systems [39][40][41][42]. This mean that cubesats could be exploited in future Moon exploration missions, as happened ìn the fall 2018 with the Mars Cube One (MarCO) satellites.…”

This paper presents a feasibility study for a very high data rate receiver operating in the K/Ka-band suitable to future Moon exploration missions. The receiver specifications are outlined starting from the mission scenario and from a careful system analysis. The designed architecture uses a low noise front-end to down-convert the incoming K/Ka-band signal into a 3.7 GHz intermediate frequency (IF). For maximum flexibility, a software defined radio (SDR) is adopted for the I/Q demodulation and for the analog to digital conversion (ADC). The decoding operations and the data interface are carried out by a processor based on field programmable gate array (FPGA) circuits. To experimentally verify the above concepts, a preliminary front-end breadboard is implemented, operating between 27.5 and 30 GHz. The breadboard, which uses components off the shelf (COTS) and evaluation boards (EVBs), is characterized by a 46 dB gain, a 3.4 dB noise figure and a − 37 dBm input-referred 1 dB compression point. Finally, a 40 Msym / s quadrature phase shift keying (QPSK) signal is demodulated by means of a commercially available SDR, demonstrating the above concept. The importance of these results is that they have been obtained exploiting a class of miniaturized and low cost microwave integrated circuits currently available on the market, opening the way to a dense communication infrastructure on cislunar space.

This article introduces a power-efficient 24.25-71-GHz multi-band phased-array receiver supporting all allocated fifth-generation mobile network new radio (5G NR) frequency range 2 (FR2) bands at 24/28/39/47 GHz and the potential 5G NR-U bands in unlicensed 57-71 GHz. A novel harmonic-selection technique is introduced to extend the operating bandwidth with low power consumption. By switching between the fundamental-selected mode, the second-harmonicselected mode, and the third-harmonic-selected mode, only signals in the desired bands can be preserved, while the unselected mixing components are rejected. A dual-mode multi-band lownoise amplifier (LNA) based on a configurable transformer is adopted to realize broadband operation with minimized power consumption and noise figure (NF). The Hartley architecture is employed to further improve the image rejection performance. A hybrid-type polyphase filter (PPF) with a detectorbased high-precision calibration block is utilized in this work to realize the Hartley operation with reduced insertion loss (IL). The proposed phased-array receiver is fabricated in a standard 65-nm bulk CMOS process. With the concerted efforts of all components, the proposed multi-band receiver can support 5G standard-compliant OFDMA-mode modulated signals up to 256QAM with a 400-MHz channel bandwidth from 24 to 71 GHz. Better than 36-dB inter-band blocker rejections can be maintained by this work. With existing of 0-dBc inter-band blockers at worst case frequencies, this receiver

“…The 6dB loss to 50Ω external node is due to high output impedance of driving Gm stage approximately 4 times the load impedance. The proper impedance transformation with good output matching required additional passives for matching [5]. However, due to area limitation only single transformer was utilized to keep wideband frequency response at the output.…”

Current millimetre-wave (mmW) 5G NR standard supports multiple bands at 24.5/28/37/39/43/47GHz for communications. To cover several bands of the 5G NR and reaching lower end of unlicensed 60GHz band for 802.11ad, this work presents a wideband phased array front-end with LNA and two VGAs for scalar-only weighting function, and a wideband combining network of each signal weight in mmW domain for beamforming. In this work, two array elements are combined in two cascaded stages for extremely wideband operation. Combined load resonances are distributed and adjusted appropriately in each of the combining stages to achieve a flat response over the band of 38.5-60.5GHz. A single array path achieves rms gain of 8.5-12.5dB, noise figure of 6.2-8.1dB, and IP1dB of -33 to -26dBm. The measurements show ≈ 6dB of array gain when the two phased array elements are combined in phase with +0.6dB to -0.4dB maximum gain error in the mmW VGAs. The prototype is implemented using 28nm CMOS.
