Impedance Matching Probes for Wireless Applications

Abstract

This work describes the motivation, technology, design, and performance of impedance matching probes that address the needs of wireless applications. The impedance matching solution can be implemented in two distinctly different technologies, air-coplanar and thin-film membrane. Impedance matched probes offer improved load-pull characterization of power, gain and efficiency, and accurate characterization of devices with non-standard impedances.
