Abstract
Official abstract text for this publication.
A wireless electronic device may contain at least one antenna tuning element for use in tuning the operating frequency range of the device. The antenna tuning element may include radio-frequency switches, continuously/semi-continuously adjustable components such as tunable resistors, inductors, and capacitors, and other load circuits that provide desired impedance characteristics. A test station may be used to measure the radio-frequency characteristics associated with the tuning element. The test station may provide adjustable temperature, power, and impedance control to help emulate a true application environment for the tuning element without having to place the tuning element within an actual device during testing. The test system may include at least one signal generator and a tester for measuring harmonic distortion values and may include at least two signal generators and a tester for measuring intermodulation distortion values. During testing, the antenna tuning element may be placed in a series or shunt configuration.
First claim
Opening claim text (preview).
What is claimed is: 1. A radio-frequency test system for testing an adjustable antenna tuning element, comprising: a first signal generator that is configured to provide first radio-frequency signals at only a first frequency to the adjustable antenna tuning element; a second signal generator configured to provide second radio-frequency signals at only a second frequency that is different than the first frequency to the adjustable antenna tuning element; and a first load pull…
