POWER OSCILLATOR USING GAN POWER AMPLIFIER

Title:

POWER OSCILLATOR USING GAN POWER AMPLIFIER

Document Type and Number:

WIPO Patent Application WO/2019/221324

Kind Code:

A1

Abstract:

The present invention provides a power oscillator using a GaN power amplifier which is composed of a gallium nitride (GaN) device, and comprises: a GaN power amplifier for amplifying and outputting the power of an input signal; a directional coupler for providing a portion of an output signal of the GaN power amplifier as a feedback signal; a phase shifter for varying a phase of the feedback signal provided by the directional coupler; and a first isolator for adjusting an impedance mismatch by the phase shifter and transmitting the feedback signal to the GaN power amplifier.
