Methods And Apparatus For Performing Passive Antenna Testing With Active Antenna Tuning Device Control

US Patent:
2014017, Jun 26, 2014
Filed:
Dec 21, 2012
Appl. No.:
13/725769
Inventors:
- Cupertino CA, US
Anand Lakshmanan - Sunnyvale CA, US
Jayesh Nath - Milpitas CA, US
Matthew A. Mow - Los Altos CA, US
Mattia Pascolini - Campbell CA, US
Vishwanath Venkataraman - Pleasanton CA, US

Assignee:
Apple Inc. - Cupertino CA
International Classification:
H04W 24/00
US Classification:
455 6714, 455 6711
Abstract:
A wireless electronic device may contain at least one adjustable 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 system that is used for performing passive radio-frequency (RF) testing on antenna tuning elements in partially assembled devices is provided. The test system may include an RF tester and a test host. The tester may be used to gather scattering parameter measurements from the antenna tuning element. The test host may be used to ensure that power and appropriate control signals are being supplied to the antenna tuning element so that the antenna tuning element is placed in desired tuning states during testing.
