Nonreciprocal components are ubiquitous in electronic and optical systems. To date, the use
of magneto-optical materials has been the prevailing method to achieve nonreciprocity …

In this paper, we discuss the design rationale and guidelines to build magnet-less circulators
based on spatiotemporal modulation of resonant junctions consisting of first-order bandstop …

This paper presents a novel dual mode configurable and tunable power amplifier (PA) that
achieves a wide-bandwidth and high gain across a operational frequency spectrum of 20 to …

This paper presents a multi-band multi-mode class-AB power amplifier, which utilizes
continuously tunable input and output matching networks integrated in a low-loss silicon-on …

To preserve link quality of mobile phones, under fluctuating user conditions, an adaptively
controlled series-LC matching circuit is presented for multi-band and multi-mode operation …

The link quality of mobile phones suffers from antenna mismatch due to fluctuating body
effects. Techniques for adaptive control of impedance-matching L networks are presented …

This paper presents a novel adaptive power amplifier (PA) architecture for performing
dynamic-load-modulation. For the first time, a dynamically-load-modulated PA design that …

Two miniaturized tunable filters with two zeros to result in sharp skirts were developed at 1.4-
2.0 GHz on epsiv r= 6.15 substrate. The filters were built using single and back-to-back …

This paper theoretically and experimentally investigates frequency-tuned and impedance-
tuned wireless non-radiative power-transfer (WNPT) systems. Closed-form expressions for …

A well-known component of RF systems is the circulator, a three-port device that allows
signals to flow in one direction while inhibiting propagation in the reverse direction …
