Oscillator with a relatively high output power - has a first power oscillator with a Gunn diode synchronised with a further oscillator

摘要

The synchronisation is operative within a specified pulling range. The further oscillator frequency is an n-th harmonic of the power oscillator fundamental frequency, and this synchronising oscillation is directly applied to the Gunn diode. The power oscillator is connected to the further oscillator through a circulator with at least three arms, with the third arm connected to the load. The power oscillator input impedance is matched at the fundamental frequency and at the n-harmonic.
