Radio frequency communication devices and methods |
摘要 |
One embodiment relates to a radio frequency (RF) communication device. The RF communication device includes an antenna interface coupled to an antenna that exhibits a time-varying impedance. The RF communication device also includes a test interface coupled to RF test equipment that exhibits a test impedance. A tuning circuit in the RF communications device selectively provides a matched impedance to either the time-varying impedance or the test impedance based on feedback derived from the test interface. Other methods and systems are also disclosed. |
