Mode-based antenna tuning

摘要

Exemplary embodiments are related to antenna tuners. A device may include a transceiver configured to operate in a frequency division duplex (FDD) network. The device may also include an antenna tuner coupled to the transceiver. Further, the device includes a processor configured to tune the antenna tuner for a receive frequency if the device is operating in receive mode and tune the antenna tuner for a transmit frequency if the device is operating in a transmit and receive mode.

主权项

1. A device, comprising:
a transceiver configured to operate in a frequency division duplex (FDD) network; an antenna tuner coupled to the transceiver; and a processor configured to selectively tune the antenna tuner to one of a receive frequency and a transmit frequency based on whether the device is operating in a receive mode and whether the device is operating in a first communication standard or a second communication standard, wherein the processor is further configured to:
determine whether the device is operating in the first communication standard;tune the antenna tuner to the receive frequency according to the first communication standard if the device is operating in the receive mode and the first communication standard;tune the antenna tuner to the transmit frequency according to the first communication standard if the device is operating in a transmit and receive mode and the first communication standard; andtune the antenna tuner to the receive frequency according to the second communication standard if the device is not operating in the first communication standard.
