空中桥实现有两种主要类型。指出了两种类型的不同电气行为。测量结果表明存在显着的损耗和相移。每种类型的多种修改都建立在 GaAs 衬底上。提供了改进单片微波集成电路 (MMIC) 设计的一些提示。空气桥 T 形接头作为新组件引入。采用共面波导 (CPW) 技术制造的行波放大器 (TWA) 作为使用最少数量空气桥的设计示例。
Two principle types of air bridge realizations are distinguished. The different electrical behaviour of both types is pointed out. Measurements indicate significant losses and phase shifting. A variety of modifications of each type is built on GaAs substrate. Some hints for improved monolithic microwave integrated circuit (MMIC) design are offered. The air bridge T-junction is introduced as a new component. A travelling-wave amplifier (TWA) fabricated in coplanar waveguide (CPW) technique is presented as a design example using a minimum number of air bridges.
