β¦ Synopsis
This paper reviews and extends the design procedures developed recently for a broad class of multilayer microwave circuits such as couplers, filters, and baluns. Multilayer configurations are now becoming increasingly popular at microwave frequencies due to the several advantages over single-layer configurations. However, systematic design procedures for implementing multilayer circuits have not been available. Examples of multilayer circuits are presented for verifying the extended design procedures. The design procedure reported earlier for coupled line multilayer filters in a homogeneous dielectric substrate environment has been extended to inhomogeneous multilayered microstriplike configurations. Modified procedure is verified by comparing the results with a full-wave electromagnetic simulation.

In this paper, the stability criteria are used to graphically determine the startup of oscillation in a Smith chart. This approach is suitable for slightly unstable circuits near the resonated frequency. In practice, an a¨ailable design of a microwa¨e two-port oscillator is presented here.
