Abstract
A reflectometer may include two directional couplers configured in parallel by being disposed across from each other on opposite sides of a shared section of a signal line. One of the couplers may couple, to a first port of the reflectometer, a portion of the signal power of a first signal flowing from the first end of the shared through-line to the second end of the shared through-line, and the other coupler may couple, to a second port of the reflectometer, a portion of the signal power of a second signal flowing from the second end of the shared through-line to the first end of the shared through-line. The reflectometer benefits from reduced size and signal loss relative to a serial coupler configuration. When used in vector network analyzer (VNA) systems, this results in higher output power and higher dynamic range of the VNA.
