Abstract
Disclosed are switching circuits and methods that enable a device to switch between two wireless protocols with antenna sharing. In some implementations, the device may use two different wireless protocols concurrently and with high isolation. In some implementations, the device can be provided with insertion loss matched transmission diversity for one of the wireless protocols. In some embodiments, various signal paths and related switches that allow such functionalities can be implemented on a single die such as a silicon-on-insulator (SOI) die.
