摘要： An electronic device may include an adjustable power supply, at least one antenna, and associated antenna tuning circuitry. The antenna tuning circuitry may be an integral part of the antenna and may include a control circuit and at least one tunable element. The tunable 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. The power supply may provide power supply voltage signals to the antenna tuning circuitry via inductive coupling. The power supply voltage signals may be modulated according to a predetermined lookup table during device startup so that the control circuit is configured to generate desired control signals. These control signals adjust the tunable element so that the antenna can support wireless operation in desired frequency bands.

摘要： A device under test (DUT) may be tested using a radio-frequency test station. The DUT may include at least one antenna, wireless communications circuitry associated with the antenna, and other peripheral components such as a camera module, a display module, and audio circuitry. The test station may include a shielded enclosure in which the DUT is placed during testing. The DUT need not be electrically wired to any test equipment. The DUT may be configured to operate in self test mode. The DUT may be configured to obtain baseline noise floor measurements while all the peripheral components are deactivated and may be configured to obtain elevated noise floor measurements while selectively activating desired subsets of the peripheral components. The difference between the elevated and baseline noise floor measurements may be computed to determine whether at least some of the peripheral components negatively impact the antenna performance by an excessive amount.
