The antenna tuning element may include radio-frequency switches, continuously/semi-continuously adjustable components such as tunable resistors, inductors, and capacitors, etc. A test system may be used to measure the radio-frequency characteristics associated with the tuning element assembled with an electronic device. The test system may include a test host, a test chamber, a signal generator, power meters, and radio-frequency testers. The electronic device under test (DUT) may be placed in the test chamber. The signal generator may generate radio-frequency test signals for energizing the antenna tuning element. The power meters and radio-frequency testers may be used to measure conducted and radiated signals emitted from the DUT while the DUT is placed in different desired orientations. A phantom object is optionally placed in the vicinity of the DUT to simulate actual user scenario.

摘要： A test system for testing an antenna tuning element is provided. The test system may include a tester, a test fixture, and a probing structure. The probing structure may include probe tips configured to mate with corresponding solder bumps formed on a device under test (DUT) containing an antenna tuning element. The DUT may be tested in a shunt or series configuration. The tester may be electrically coupled to the test probe via first and second connectors on the test fixture. An adjustable load circuit that is coupled to the second connector may be configured in a selected state so that a desired amount of electrical stress may be presented to the DUT during testing. The tester may be used to obtain measurement results on the DUT. Systematic effects associated with the test structures may be de-embedded from the measured results to obtain calibrated results.
