Coplanar waveguides on silicon substrate were simulated. Using MEMS (micro-electro-mechanical system) technology, the V-shaped and W-shaped groove coplanar waveguides were implemented on silicon substrate, and its characteristic impedance was 30Ω, 50Ω, 75Ω and 100Ω respectively. In addition, the characteristic impedance of coplanar waveguide (CPW) was analyzed, and the conclusion was used to guide...
BAW (bulk acoustic wave) filters have emerged as an important technology for GHz filtering components. Especially the high quality factor and the good temperature coefficient make BAW filters well suited for W-CDMA band 2 and band 3 devices. During the design phase it is essential to analyze and minimize possible loss mechanisms to meet the high requirements of these devices. Well known loss mechanisms...
