摘要

PROBLEM TO BE SOLVED: To provide an analyzer and a method improved for analyzing a behavior of an electronic device with respect to a high frequency input signal, and an improved method for designing and manufacturing a high frequency device.;SOLUTION: An active load pull circuit 201 receives an output signal from a DUT 206, provides a changed signal to the DUT 206 at that time, and is connected to the DUT 206 from which the signal is returned. That signal is changed by an analog signal processing circuit 237 when input signals x and y are considered, and an amplitude gain and a phase change operated in a feedback circuit 237 are controlled. Therefore, a positive feedback loop is avoided and better control for control of analysis is enabled. A network analyzer or any other signal measuring device 242 records a waveform observed in a port of the DUT 206, and behaviors of the DUT 206 under various load conditions are analyzed as a result.;COPYRIGHT: (C)2012,JPO&INPIT
