Determining characteristics of frequency translation devices by extracting expressions from reflection responses including variations in sum and difference signal components

摘要

The process involves applying a stimulus signal to a first gate of the frequency translation device (4) and a drive signal (7) to a second gate (2), while a third gate that delivers a sum and difference component is connected to the input of a filter. Three reflection responses are obtained that include variations in the sum signal component or difference signal component, depending on if one of three terminals is connected to the output of the filter (6). Flow diagram expressions (R1,R2,R3) are extracted for the translation device (4) and the filter (6) from the reflection responses.
