Small-Signal Theory of the Gyro-BWO With the Zigzag Quasi-Optical System

We describe the small-signal theory of a backward-wave gyro-oscillator with a sectioned quasi-optical system with the zigzag path of the operating wave beam. This theory explains peculiarities (namely, a piecewise character) of changing the operating frequency and power of the output signal in the process of the broadband frequency tuning provided by changing the operating magnetic field.
