The Influence of the Package Environment on the Functioning and Reliability of Capacitive RF-MEMS Switches

This article discusses the influence of the packaging process and environment on the functioning and reliability of capacitive RF-microelectromechanical systems (MEMS). It is shown that the packaging temperature profile can change the mechanical stress...
RF-MEMS switches offer a number of advantages for switching in the gigahertz range because of their low insertion loss, high linearity and low power consumption. 1 Several publications have reported on the performance of such switches, but more for non-packaged ‘naked’ samples. It is clear that the packaging process...

RF Linear Power Amplifier Gain Stabilization Over Ambient Temperature

This article discusses the influence of the packaging process and environment on the functioning and reliability of capacitive RF-microelectromechanical systems (MEMS). It is shown that the packaging temperature profile can change the mechanical stress...
The temperature stability of the RF output power level has become especially important for different handheld wireless communication systems. For GSM mobile handsets, an analog closed-loop power control, incorporated in the transmitter power amplifier (PA) chain, allows the main parameters of the PA to be stabilized over the ambient...
