Planning of hybrid integrated circuits for microwave-band oscillators

An analytical method to calculate the hybrid integrated circuits (GIS) of microwave band oscillators based on field effect transistors with a Schottky gate (PTSh), which uses a transmission matrix of noise waves and parameters of the PTSh is presented. The following items are considered: (1) spreading and transmission matrices in large signal operation; (2) noise parameters of PTSh with feedback; (3) parameters of tuned circuit and matching network; (4) AM and FM noise of GIS oscillators; and (5) development of low noise GIS oscillators. The analysis made of microwave band GIS oscillators based on PTSh concluded that use of noise waves and noise parameters makes it possible to calculate the AM and FM noise of microwave band GIS oscillators and to forecast their behavior for PTSh with varied feedbacks.
