Phased Array in mm-Wave and Sub-THz for Communication and Sensing

At the mm-wave frequency, the broad bandwidth spectrum challenges the RF circuits on the specification of the bandwidth, gain, and efficiency. Those are design art and trade-offs for the RF-FE circuit, such as LNA, phase-shifter, and power amplifier. This talk will discuss a design methodology for broadband circuits, and a series of state-of-the-art circuits based on this design methodology will be presented. The broadband circuits and systems provide benefits to joint communication and sensing at sub-THz.
