“…Therein, quiet Sun refers to the absence of solar flares. The DC voltage at the output can be evaluated as follows [37] : 𝑉𝑉 𝑜𝑜𝑠𝑠𝑜𝑜 = 𝑘𝑘 𝐵𝐵 ℜ𝐵𝐵𝐵𝐵(𝑇𝑇 𝑁𝑁 − 𝑇𝑇 𝐴𝐴 ) (8) According to (8), quiet Sun corresponds to an output voltage of 0 V; 1000 sfu, i.e. a small entity solar flare, corresponds to 0.32 mV; and 1001 sfu, corresponds to 0.35 mV.…”

“…The two advantages of the Dicke balanced radiometer are that 1) the ΔG/G effect is removed, and 2) the flicker noise at the receiver output is modulated around ±f s thus drastically reducing the noise within the integrator bandwidth. As a downside, the two disadvantages are that 1) the observation time is only half of the operating time, and 2) the switch causes a reduction of the system gain and an increment of the noise figure [37] .…”

Solar flares, intense bursts of radiation, can disrupt the atmosphere and potentially affect communication, navigation and electrical systems. A newly developed miniaturised microwave radiometer used on a space-borne platform should offer astronomers unprecedented understanding of the largest explosive phenomena in our solar system. In this paper the activity and results of the EU funded research project FLARES are presented. Objective of FLARES has been the study, analysis and design of millimetre-wave (mm-wave) system-on-chip (SoC) radiometer for space-borne detection of solar flares. The proposed approach has contributed to reduce significantly the power consumption and weight with respect to the existing instruments for the observation and study of solar flares. In particular, the proposed SoC Dicke radiometer can achieve one order of magnitude improvement in terms of resolution, so allowing the detection of solar flares with relatively low intensity, i.e. about 100 times lower than those currently detected by the existing systems, owing to space-borne operations and the microchip-level miniaturization through silicon technology under space qualification.

“…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.…”

K/Ka-Band Very High Data-Rate Receivers: A Viable Solution for Future Moon Exploration Missions

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.

“…Yet these receivers are only for the communication purpose, not supporting a radiometric function capable of dynamically measuring the atmospheric conditions. Certainly some microwave and millimeter-wave radiometers were presented to sense the atmospheric conditions and realize passive imagers [6], [27][28][29][30][31][32]. However, they only provide the radiometric function without any wireless communication capability.…”

A highly-integrated reconfigurable Ka-band receiver in a 90-nm CMOS technology is proposed for the applications of satellite wireless communications, remote sensing of atmospheric conditions, and detection of space debris. The proposed receiver can be reconfigured to support active-receiver and passivereceiver modes. At the active-detection mode, it works as a direct-conversion coherent receiver for highspeed and global-coverage satellite communications. Measured conversion gain of 45.2 dB, noise figure of 7.6 dB, and output 1-dB compression point of -6.8 dBm can be acquired at 35 GHz while only consuming 54.4 mW from a 1.2-V supply. As switched to the passive-detection mode, it can potentially operate as a noncoherent radiometer to sense atmospheric conditions which are employed to dynamically compensate the atmospheric attenuation to mitigate the fading effects. This enables the satellite communication systems to establish reliable links. Moreover, the proposed passive receiver can be utilized to detect the space debris. Collisions can be avoided and hence satellite lifetime can be enhanced. Experimental results show that the proposed receiver at the passive-detection mode exhibits voltage responsivity of 1.2 GV/W and noise equivalent power (NEP) of 2.1 aW/Hz 0.5 at 35 GHz. The power dissipation is only 49.6 mW from a supply voltage of 1.2 V. To the best of the authors' knowledge, the proposed receiver owns the highest responsivity and the lowest NEP at Ka-band reported thus far. It is also the first receiver capable of being reconfigured to support active-detection and passive-detection modes according to different application scenarios.INDEX TERMS Reconfigurable, Ka-band, CMOS, active receiver, passive receiver, satellite communications, radiometer, effect of fading, space debris.
