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.

First claim

What is claimed is:

1. A switching circuit comprising:
a first signal path between a transmit terminal and a first antenna terminal, the first final path including a first switch and an insertion loss component electrically connected in series;
a second signal path between the transmit terminal and a second antenna terminal, the second signal path including a second switch and a third switch electrically connected in series, the switching circuit configured to be capable of oper…
