Multi-standard transceiver architecture with common balun and mixer
First Claim
1. A multi-standard transceiver operative to transmit signals using either a first communication standard or a different second communication standard, the transceiver comprising:
- a balun comprising a primary coil and a secondary coil;
a controller configured to control which communication standard is used by the multi-standard transceiver for signal transmissions;
at least one first switch operative to connect the primary coil of the balun to a first signal path associated with the first communication standard or a second signal path associated with the second communication standard responsive to a control signal provided by the controller;
at least one second switch operative to connect the secondary coil of the balun to a first amplification path associated with the first communication standard or a second amplification path associated with the second communication standard responsive to a control signal provided by the controller; and
a mixer configured to;
output upconverted signals associated with the first communication standard to the first signal path responsive to a control signal output by the controller when the multi-standard transceiver operates according to the first communication standard; and
output upconverted signals associated with the second communication standard to the second signal path responsive to a control signal output by the controller when the multi-standard transceiver operates according to the second communication standard.

Abstract
A multi-standard transceiver comprises a common balun, a controller, at least one first switch, and at least one second switch. The common balun comprises a primary coil and a secondary coil. The at least one first switch connects the primary coil of the balun to a first signal path associated with a first communication standard, or to a second signal path associated with a second communication standard responsive to a control signal provided by the controller. The at least one second switch connects the secondary coil of the balun to a first amplification path associated with the first communication standard, or to a second amplification path associated with the second communication standard responsive to a control signal provided by the controller. A common mixer is configured to provide upconverted signals to one of the signal paths depending on which communication standard has been selected.

7. A method of operating a transceiver to use either a first communication standard or a different second communication standard, the transceiver comprising a common mixer and a common balun that are utilized in signal processing operations for both of the communication standards, the method comprising:
-
outputting, via the common mixer, upconverted signals associated with a selected one of the communication standards; controlling at least one first switch to selectively connect a primary coil of the balun to the upconverted signals via either a first signal path corresponding to the first communication standard, or a second signal path corresponding to the second communication standard, responsive to the communication standard selection; and controlling at least one second switch to connect a secondary coil of the balun to either a first amplification path associated with the first communication standard or a second amplification path associated with the second communication standard, responsive to the communication standard selection. - View Dependent Claims (8, 9, 10, 11)
