Abstract

The invention provides anonlinear Sparameter standard harmonic wave signal output circuit and device. By controlling the delay of an input signal, a narrow pulse outputted by a conjunction gate generates rich harmonic components, a harmonic signal with stable amplitude-phaseis realized through control of passive delay and input signal shaping;the rich and stable harmonic signal can be accurately determined by a nonlinear network analyzer and taken as a measurement standardto perform detection of the nonlinear Sparameter of the nonlinear network analyzer; and according to the nonlinear Sparameter standard harmonic wave signal output circuit and device,a standard harmonic signal output circuit of the nonlinear Sparameter is utilized to compensate for the problem that a current linear Sparameter standard does not generate new frequency components, can only verify the amplitude-phase of a fundamental signal, and cannot verify the amplitude-phase of each harmonic wave outside the fundamental wave.

Description

technical field [0001] The invention relates to the technical field of circuit design, and more specifically, relates to a non-linear S parameter standard harmonic signal output circuit and a device. Background technique [0002] RF microwave systems are usually composed of active devices and passive devices, and active devices often have nonlinear characteristics, that is, new frequency components are generated. The research and design of such high-performance RF active devices poses a challenge to designers. The key issue is how to characterize the nonlinear characteristics of the device, so as to reduce the adverse effects of the nonlinearity of the device, or make use of it. Provides a linear, high-efficiency high-power solution. Amplifier is an indispensable component in the field of wireless communication. Due to its nonlinear characteristics, spectrum is often wasted; if the power amplifier is designed to work only in its linear region in order to consider the effici...
