Receiver with bypass mode for improved sensitivity
First Claim
1. An apparatus comprising:
- a non-bypass signal path coupled to a receiver, the non-bypass signal path comprising a filter;
a bypass signal path coupled to the receiver, the bypass signal path configure to bypass the filter;
a processor configured to output a control signal that indicates predetermined time intervals when signals are transmitted by a related local transmitter with a signal power that exceeds a selected threshold, the control signal output prior to the signal being received; and
a switch configured to receive the control signal, and in response, to couple an antenna to the non-bypass signal path during the predetermined time intervals and to couple the antenna to the bypass signal path during other time intervals.

Abstract
A receiver with bypass mode for improved sensitivity is disclosed. An apparatus is provided that includes a non-bypass signal path coupled to a receiver, the non-bypass signal path comprising a filter, a bypass signal path coupled to the receiver, the bypass signal path configure to bypass the filter, and a switch configured to couple an antenna to the non-bypass signal path during time intervals when signals transmitted by a related local transmitter are transmitted with a signal power that exceeds a threshold, and to couple the antenna to the bypass signal path during other time intervals. In another aspect, the switch is configured to couple the antenna to the non-bypass signal path during time intervals when a jamming signal in a selected frequency range is received with a signal power that exceeds a threshold, and to couple the antenna to the bypass signal path during other time intervals.

9. A method comprising:
-
detecting whether a local transmitter is to transmit a signal with a signal power that exceeds a selected threshold; enabling a non-bypass mode prior to receiving the transmitted signal if the local transmitter is to transmit the signal with the signal power that exceeds the selected threshold; and enabling a bypass mode prior to receiving the transmitted signal if the local transmitter will not transmit the signal with the signal power that exceeds the selected threshold. - View Dependent Claims (10, 11, 12)
