In this paper, we present small and large signal data of a switched LNA hybrid circuit implemented using a low-loss and high linearity RF MEMS switching network on a GaAs MMIC wafer. The GaAs MEMS based reconfigurable LNA front-end circuit can achieve a 30 dB difference in in-band gain and attenuation (when the switch is turned on and off) while also being able to maintain a high gain (low noise figure)...
RF-MEMS is an emerging area of MEMS technology that is revolutionizing RF- and microwave applications. RF-MEMS devices have a broad range of applications in military and commercial wireless communication, navigation and sensor systems. Agile RF-systems require reconfigurable frontends that can steer the beam over a wide frequency range. Such applications always require some kind of switches. The RF...
