Abstract
This document describes a program for numerically predicting the performance of hundereds of millimeter wave oscillators that are combined through quasi-optical techniques. The focus of this program will be on combining three terminal field effect transistors. The basis of the analysis centers around the inter-ijection locking of canonical oscillators. Among the issues to be addressed during the Phase I are: (1) What is the locking bandwidth of the systemof injection locked oscillators? (2) After an initial turn-on transient, how many cycles are needed before the oscillators synchronize to a common frequency and phase? (3) Are there restrictions on the distribution of amplitudes of the oscillators in order to achieve synchronization? (4) How will device and circuit variations influence the locking properties? (5) What constraints are to be imposed to operate the couple-oscillator arrays as mode-locked arrays? (6) Choices of oscillator configurations. (7) Best use of Fabry-Perot resonators. (8) Limitations on packing density. The out of the calculations will also provide (1) the radiation paterns for a finate set of coupled oscillators, for prespecified values of the coupling phase; and (2) the time dependence of the output signal power envelop of a number of mode locked oscillators.
