Microwave Transistors

Microwave Transistors: Silicon bipolar transistors were first on the microwave scene, followed by GaAs field-effect transistors. Indeed, FETs now have noticeably lower noise figures, and in the C band and above they yield noticeably higher powers. A description of Microwave Transistors constructions and a discussion of their performance now follow. Transistor Construction: The various factors […]

Stripline and Microstrip Transmission Line

Stripline and Microstrip Transmission Line: Stripline and Microstrip Transmission Line are physically related to transmission lines but are covered here because they are microwave circuits used in conjunction with semiconductor microwave devices. As illustrated of Stripline and Microstrip Transmission Line shown in Figure 12-1, stripline consists of flat metallic ground planes, separated by a thickness […]
