Phase Noise Measurement of RF Devices Using Full Digital Phase Noise Measurement Method

Abstract

In this paper, we propose a new method for measuring the phase noise of RF devices using a full digital phase noise measurement method. We verified that the phase noise of an RF device could be measured by inserting a device under test (DUT) as part of the full digital phase noise measurement setup. A phase shifter in the 10 MHz band was used for the DUT, and its phase noise characteristics were measured.
