Abstract :
A two-mode tuning method for injection locked oscillators at microwave frequencies is presented. This technique allows one to modify the frequency response characteristics and stability boundary of an injection locked oscillator (ILO) in a favorable direction. Using this idea, a lock-in microwave discriminator has been proposed. Both a mathematical and experimental results on the stability properties, tracking zone, and other characteristics of the discriminator are presented
