Abstract
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.
