WIRELESS MULTIMODE CO-BAND RECEIVER DEVICE AND METHOD EMPLOYING RECEIVER BYPASS CONTROL
First Claim
1. In a device having a first radio access technology (RAT) receiver and a second RAT receiver that use a shared signal receive path that includes at least one shared receiver component, a method comprising:
- determining if a single RAT receive mode of operation or a multi-RAT receive mode of operation is desired; and
if a single RAT receive mode of operation is desired, bypassing the at least one shared receiver component from a receive path for a corresponding RAT receiver used for the single mode of operation.

Abstract
A wireless multimode radio access technology (RAT) handheld device (100) utilizes first and second wireless radio access technology receivers (108 and 110) includes at least one shared receiver component (120 or 121 or 123) that is within a shared receive path that is shared by both the different RAT receivers (108 and 110) when in a multimode receiver operation. The handheld device (100) includes a radio access technology bypass switch (106) and corresponding logic (112), that controls the RAT bypass switch to bypass the at least one receiver component (120 or 121 or 123) that is shared between the first and second RAT receivers (108 and 110), when the handheld device is in a single RAT receive mode of operation. A method is also disclosed that includes determining (202) if a single RAT receive mode of operation or a multi-RAT receive mode of operation is desired. The method also includes bypassing (204) at least one shared receiver component from a receive path for a corresponding RAT receiver used for the single mode of operation.

11. A wireless multimode radio access technology (RAT) handheld device comprising:
-
at least an antenna transmit/receive switch operatively coupled to an antenna; at least first and second wireless radio access technology (RAT) receivers, operatively coupled to the antenna transmit/receive switch, that use a shared signal receive path that includes at least one shared receiver component; a RAT bypass switch, operatively coupled to the second RAT receiver and to the antenna transmit/receive switch, with a first position operative to couple the second RAT receiver to the at least one shared receiver component and a second position operative to bypass the at least one shared receiver component; and logic operative to control the RAT bypass switch and the antenna transmit/receive switch to bypass the at least one shared receiver component if a single RAT receive mode of operation is desired using the second RAT receiver. - View Dependent Claims (12, 13, 14, 15)

16. A wireless multimode radio access technology (RAT) handheld device comprising:
-
at least an antenna transmit/receive switch operatively coupled to an antenna and including a single RAT mode switch operation; at least first and second wireless radio access technology receivers; a low noise amplifier (LNA) and a signal splitter, the amplifier having an input operatively coupled to the antenna transmit/receive switch through a WCDMA duplexer and an output operatively coupled to the signal splitter, the signal splitter having a first output operatively coupled to the first RAT receiver and a second output; a radio access technology (RAT) bypass switch, operatively coupled to the antenna transmit/receive switch, to the second output of the signal splitter and to the second RAT receiver; and logic operative to control the RAT bypass switch and at least the antenna transmit/receive switch to bypass the amplifier and signal splitter if a single RAT receive mode of operation is desired using the second RAT receiver. - View Dependent Claims (17, 18, 19)
