An Empirical Large-Signal Model for SiC MESFETs With Self-Heating Thermal Model Kelvin S. Yuk, Student Member, IEEE, and George R. Branner, Life Member, IEEE Abstract--An empirical large-signal model for high-power microwave silicon-carbide MESFETs capable of predicting self-heating thermal behavior is presented. A generalized drain-current equation based on pulsed-gate IV characteristics measurin

An Active Guarding Circuit Design for Wideband Substrate Noise Suppression Hao-Ming Chao, Wen-Shen Wuen, Member, IEEE, and Kuei-Ann Wen, Member, IEEE Abstract--In this paper, an active guarding circuit is presented for wideband substrate noise suppression. A feed-forward compensation mechanism is proposed to extend the noise suppression bandwidth and to adjust the amplitude of phase-inversed noise

Amplifier Nonlinear Modeling with RF Pulses Carlos Crespo-Cadenas, Associate Member, IEEE, Javier Reina-Tosina, Member, IEEE, and Mara J. Madero-Ayora, Student Member, IEEE Abstract--This paper proposes a Volterra kernel identification procedure for wireless amplifiers with nonlinear memory. The technique is based on a reduced-order Volterra model for wideband amplifiers that is favorably compare

A Design Technique for Concu Harmonic Tuned Power Paolo Colantonio, Franco Giannini, Rocco Giofrè, Student M Abstract--In this paper, a novel technique to design concurrent dual-band high-efficiency harmonic tuned (HT) power amplifiers (PAs) is presented. The proposed approach is based on a methodology developed to design multifrequency passive matching networks, which allows concurrent operabili

Coupling Mechanism in Hybrid SIW--CPW Forward Couplers for Millimeter-Wave Substrate Integrated Circuits Andreas Patrovsky, Member; IEEE, Maxime Daigle, and Ke Wu, Fellow, IEEE Various publications address the suppression of the ,de coupling in laterally bounded conductor-backed guides (CPWs). In this paper, we present an inte,,tide structure in which this coupling effect of difmodes is deliberate
