Abstract: An apparatus includes a temperature measuring device within a thermally conductive package. A crystal within the package is thermally coupled to the temperature measuring device and subjected to a same temperature as the temperature measuring device. A controller external to the package is configured to receive a signal from the crystal and a temperature measurement from the temperature measuring device. The controller is configured to estimate a frequency error of the crystal based on the temperature measurement and to provide a frequency error estimate to an external system.

Abstract: Methods and apparatus are provided for allowing a transmitter (Tx) to perform antenna selection independently of a receiver (Rx) in a transceiver supporting both transmit diversity and receive diversity. Certain aspects may utilize a cross switch, which may be used in a parallel or cross configuration, to provide for the independent antenna selection, such that the Rx may maintain the ability to operate on the same antenna as the Tx, on another antenna, or on both antennas for enhanced receive diversity. Furthermore, certain aspects may employ additional switching in the baseband domain in an effort to avoid, or at least reduce, switching glitches in the Rx caused by changing the cross switch configuration. In this manner, the Rx need not re-converge upon antenna switching.
