Summary: This letter presents a D-band frequency-modulated continuous wave (FMCW) radar for industrial and scientific applications. The radar has an ultrawide frequency range and can be used for dual polarization sensing as well as azimuth and elevation angle-of-arrival estimation. It provides high performance and dynamic range capabilities, making it suitable for multitarget environments and achieving high-range resolution.

Summary: This article demonstrates the implementation of 80- and 160-GHz four-channel radar sensors employing a modular scalable platform based on a single relaxed 40-GHz local oscillator and cascadable transceiver chips. The sensors offer applications such as radar imaging, ranging, velocity measurement, and data communication.

Summary: This paper presents the design and characterization of single-chip 110-170 GHz direct conversion I/Q transmitter and receiver MMICs. The transmitter consists of a power amplifier, I/Q modulator, and LO multiplier chain, with a conversion gain of 23 dB and saturated output power of 0 dBm. The receiver includes a low noise amplifier, I/Q demodulator, and x6 multiplier chain at the LO port, providing a conversion gain of 27 dB and a noise figure of 10 dB.
