(EUSR) will be presented. The transmitter beamforming, receiver beamforming, and phased array pulse-echo concepts will be developed fromfirst principles. The practical implementation of the EUSR algorithm, and experimental validation and calibration of this method will be presented. The chapter will...
To validate the proposed architecture, a single-element 56-to-66 GHz phased-array receiver front-end is fabricated in a 65-nm bulk CMOS process. Based on the measurement results, the receiver achieves a power gain of ~14.85 dB and a minimum noise figure (NF) of 5.7 dB. The measured ...
This paper presents the design of an eight-element 60 GHz phased-array receiver chip with interference mitigation capability, fabricated in 0.25 μm SiGe BiCMOS technology. Each receiver element contains a low noise amplifier (LNA) and a vector-modulator that supports high-resolution amplitude and ...
An optical phased array transmitter/receiver includes a plurality of waveguides each including an optical fiber and a light source coupled to the fibers in the waveguides. At least one grating is coupled to the fiber of each waveguide and at least one phase shifter coupled to the fiber of at...
This paper demonstrates an 8-element phased array receiver in a standard 0.18-mum SiGe BiCMOS (1P6M, SiGe HBT ft ap 150 GHz) technology for X- and Ku-band applications. The array receiver adopts the All-RF architecture, where the phase shifting and power combining are done at the RF le...
