In order to improve microwave characteristics and the frequency response of the output thermovoltage at X-band, an inline RF MEMS power sensor with the impedance matching and compensating capacitance structures is presented in the paper and the sensor is accomplished with GaAs MMIC process. The measured results show that the reflection loss of the sensor is less than -17 dB and the insertion loss...
Wideband 8-12-GHz inline-type microwave power sensors that are based on measuring the microwave power coupled from the coplanar waveguide line by a microelectromechanical systems membrane are presented. In this method, the signal is available during the power detection. In order to obtain the low reflection losses and insertion losses, as well as the wideband response of the power sensor, an impedance...
The theory, design, fabrication and measurements of a novel structure for measuring power of microwave signals are presented. The novelty of this sensor is that it measures the microwave power coupled from the CPW line by the MEMS membrane. In this method the signal is available during the power detection. The fabrication of the power sensor is fully compatible with the GaAs MMIC process. The design,...
