“…The Direct Detection (DD) configuration [8][9] typically consists of a high-gain (50 -60 dB) low-noise amplifying chain, a bandpass filter (to select the radiometer integration bandwidth), a power detector and a low frequency video amplifier with high stability performances. Its simplified block diagram is shown in Fig.…”

This paper deals with the design of fully integrated, silicon microwave radiometers according to down-conversion and direct detections architectures. The low-noise amplification stages have been developed exploiting a state-ofthe art 90nm CMOS process, thus allowing a new class of miniaturized sensors (i.e. SoC microwave radiometers) to be conceived. The LNA developed for the down-conversion radiometric architecture has been fabricated and measured showing, at 13 GHz, a power gain of 19 dB, a noise figure of 1.4 dB and a power consumption of 17.38 mW with 1.1-V supply. These figures represent one of the best set of performance among those presented, now-a-day, in the literature. Concerning the the direct detection radiometric architecture only post-layout simulations are reported. In this case the designed LNA reaches a power gain of 50 dB, a noise figure of 1.4 dB with an associated power consumption of 32 mW.

This paper presents for the first time the design, electromagnetic modeling and simulation of a W-band micromachined receiver with a double folded slot antenna. The antenna was processed on a thin dielectric membrane obtained through wet micromachining of a 400 µm thick, high-resistivity silicon substrate. A stand-alone antenna structure was fabricated and characterized in terms of reflection losses, showing a working band (defined for |S11|<-10 dB) between 88.3-105.8 GHz, in good agreement with simulations. The maximum simulated directivity at 94 GHz is 6.3 dBi. The direct conversion receiver uses a hybrid integrated GaAs zero bias detector diode. Two new parameters based on the incident isotropic power are introduced: isotropic voltage sensitivity and isotropic tangential signal sensitivity. The measured isotropic tangential sensitivity is lower than-40 dBm between 80-105 GHz, for a 10 kHz video bandwidth.

Integrated circuit receivers have been built and tested for applications at millimeter-wave frequencies. The receivers utilize a coplanar waveguide-fed double folded-slot (DFS) antenna on a high-resistivity silicon substrate lens. The 22 GHz receiver couples the antenna to a 6-stage MESFET followed by a planar Schottky-diode detector. Measurements of the system performance show a video responsivity close to 1 GV/W and a radiometer sensitivity of 3.8 tV/K. The active MIC receiver can be integrated monolithically and is readily scalable to W-band frequencies. The 94 GHz double folded-slot antenna exhibits excellent millimeter-wave patterns, demonstrating the suitability of the DFS for use at W-band. The application areas for this type of receiver are in low-cost millimeterwave linear imaging arrays for remote sensing, automobile collision-avoidance and limited-visibility aircraft landing systems.
