“…THz mixers, multipliers components and heterodyne systems are developed at LERMA-Observatory of Paris for planetary and atmospheric science applications such as the Submillimeter-Wave instrument SWI in Jupiter JUICE-L1 ESA mission [2], [3]. The strong demand of astronomers to detect ultra-low noise signals is challenging the design and optimization efforts in order to push the system's sensitivity to its best.…”

“…and detector sensitivity. In [2] and [3] we propose state-of-the-art highly optimized sub-harmonic 600 GHz and up to 1200 GHz Schottky mixers and their dedicated technology process developed at C2N-CNRS. These room-temperature mixers are specially designed to detect variation of THz radiation related to the physical temperature of optical blackbodies, at a magnitude below 0.1 Kelvin, with a spectral resolution up to 10 6 .…”

Above 300 GHz, Schottky-based room-temperature heterodyne systems allow to detect THz radiation to the order of <0.1 K of physical temperature variations in optical blackbodies with unequaled spectral resolution. In this paper we examine some of the parameters of these low-noise and highresolution detection systems in order to enhance their future use in the generation/detection of free space THz-carrier modulated signals. We propose and demonstrate a novel way to generate QPSK modulated signals through the bias voltage of the last multiplier element of the emitter chain that yet could reach > mW of emitted power and a signal bandwidth of several tenth of gigahertz.

“…Rectangular waveguides are used to couple the radio frequency (RF) signal and the LO to the anti-parallel diodes through E-probes centered in waveguides with reduced heights. The mixer topology is based on [9] where the diodes are located close to the RF E-probe. This minimizes the RF loss and thereby improves the conversion loss.…”

Atmospheric science based on space-borne millimeter wave measurements require reliable and state-of-theart receivers. In particular, the water vapor line at 183.3 GHz motivates the development of sensitive mixers at this frequency. Traditional assembly techniques employed in the production of Schottky diode receivers involve flip-chip mounting and soldering of discrete dies, which prohibit the implementation of reliable and repeatable production processes. In this work, we present a subharmonic 183 GHz mixer implementing a repeatable assembly method using beamlead Schottky diodes. The mixer was integrated with a InP HEMT MMIC low noise intermediate frequency amplifier resulting in a record-low receiver noise temperature of 450 K at 1 mW of local oscillator power measured at room-temperature. The measured Allan time was 10 s and the third order local oscillator spurious power was less than-60 dBm. The proposed assembly method is of particular importance for space-borne missions but also applicable to a wide range of terahertz applications.

330-500 GHz Graphene-Based Single-Stage High-Order Subharmonic Mixer

In this work, a graphene-based single-stage high-order subharmonic mixer is presented. The device is able to up-and downconvert a signal in the 330-500 GHz frequency range, using a local oscillator signal with frequency located in the 26-40 GHz band. It exploits the strong nonlinear electromagnetic behavior exhibited by macroscopic graphene sheets when they are exposed to an incident electromagnetic wave to generate the output signal as a mixing product between the input signal and a high-order harmonic component of the local oscillator, which is internally generated without requiring additional circuitry. A prototype was implemented and its performance was experimentally characterized considering several different local oscillator multiplication orders. The maximum measured downconversion gain is around −50 dB, whereas the maximum output signal reached when working as upconverter is −43 dBm at 340 GHz and −63 dBm at 480 GHz. These values are good enough to be used in practical short-range applications. Furthermore, the measurement results are in good agreement with the theoretical predictions about graphene behavior.
