Abstract
A multi-band communication device with a front end antenna switch module and shared bias circuit is disclosed. Control inputs determine signal routing and amplifier biasing in response to the communication device's mode or band of operation. A received signal is routed to an active path, which corresponds to the band of the received signal. A received signal is selectively switched to one or more switch outputs, which connect to one or more filters matched to the band of the received signal. After filtering, the signal is directly provided to an active amplifier. An amplifier is activated by a bias signal received from a shared bias circuit. The shared bias circuit generates a bias signal which is selectively switched to an amplifier associated with an active path.
