We demonstrate an optimized design of a highly efficient three-stage Doherty power amplifier (PA) for the 802.16e mobile world interoperability for microwave access (WiMAX) application at 2.655 GHz. The "three-stage" Doh...
A compact ultra-wideband low-noise amplifier (LNA) with a 12.4-dB maximum gain, a 2.7-dB minimum noise figure (NF), and a bandwidth over 0.1-14 GHz is realized in a 0.13-mu m CMOS technology. The circuit is basically an ...
A silicon-based photoconductive switch and attenuator for microwave signals has been demonstrated and optimized for low insertion loss and high attenuation response upon illumination from a standard infrared LED. This de...
