Temperature-dependence of a GaN-based HEMT monolithic X-band low noise amplifier

Schwindt, R. S.; Kumar, V.; Aktaş, Ozan; Lee, J.-W.; Adesida, I. (IEEE, 2004-10)

The temperature-dependent performance of a fully monolithic AlGaN/GaN HEMT-based X-band low noise amplifier is reported. The circuit demonstrated a noise figure of 3.5 dB, gain of 7.5 dB, input return loss of -7.5 dB, and ...
Unveiling Tmax inside GaN HEMT based X-band low-noise amplifier by correlating thermal simulations and IR thermographic measurements

Zafar, Salahuddin; Durna, Yılmaz; Koçer, Hasan; Akoğlu, Büşra Çankaya; Aras, Yunus Erdem; Odabaşı, Oğuz; Bütün, Bayram; Özbay, Ekmel (IEEE, 2022-12-20)

This paper presents a method to reveal the channel temperature profile of high electron mobility transistors (HEMTs) in a multi-stage monolithic microwave integrated circuit (MMIC). The device used for this study is a ...
X-band low phase noise mmic vco & high power mmic spdt design

Osmanoğlu, Sinan (Bilkent University, 2014)

Generally the tuning bandwidth (BW) of a VCO is smaller than the tuning BW of the resonant circuit itself. Using proper components with right topology can handle this problem. In order to overcome this problem and improve ...
