This paper presents an new modeling method that RF MEMS device is divided into some typical structures, which can be considered as different transmission lines and be modeled respectively to get equivalent circuit model of the device by cascading. Applying the modeling method to DMTL, the equivalent circuit model and the relationship between model parameters and physical size are obtained after MEMS...
The characteristic study on the buck-boost and Cuk chopper circuit has an important role for optimal design of the DC-DC converter. Therefore, based on the given parameter conditions, the two chopper circuit models are constructed using software simulation integrated environment — Simulink of MATLAB, and the circuit characteristics are discussed, such as the output voltage, the circuit current and...
In this paper, a 5-bit switched-line phase shifter is designed, processed and tested for X-band application, which is based on packaged RF MEMS single-pole double-throw(SPDT) and single-pole four-throw(SP4T) switches to get an compact structure. The design and optimization are carried out by analyzing the non-ideal performance of packaged RF MEMS switches and extracting their circuit model parameters...
