Abstract

39. A method of operating a multi-mode radio receiver operable to receive first receive signals generated during operation of a first radio communication system and to receive at least second receive signals generated during operation of at least a second radio communication system, said method comprises the steps of: applying a first receive signal, if received at the multi-mode radio receiver, to a first receive chain portion (62) and a second receive signal, if received at the multi-mode radio receiver, to a second receive chain portion (64), the first receive chain portion (62) comprising a first amplifier (88) and the second receive chain portion (64) comprising a second amplifier (118); selectably acting upon the first receive signal at the first receive chain portion (62) by selectably biasing the first amplifier (88) and upon the second receive signal at the second receive chain portion (64) by selectably biasing the second amplifier (118), either one, but not both, of the first receive chain portion (62) and the second receive chain portion (64) operable during a selected period; applying a selected one of the first receive signal and the second receive signal to a common receive chain portion (66); subsequent to actions performed thereon during said operation of selectably acting; and further acting upon the selected one of the first receive signal and the second receive signal, respectively, applied to the common receive chain portion (66); further comprising the steps of: applying a third receive signal generated during operation of a third radio communication system, if received at the multi-mode radio receiver, to the second receive chain portion (64), and wherein said operation of selectably acting upon the first receive signal and the second receive signal further comprises selectably acting upon the third receive signal at the second receive chain portion (64). 40. The method of operating a multi-mode radio receiver of claim 39, wherein said operation of selectably acting upon the third receive signal further comprises selectably biasing a third amplifier (122) to allow the second receive chain portion (64) to act upon the third receive signal.

Claims (1)

  1. 39. A method of operating a multi-mode radio receiver operable to receive first receive signals generated during operation of a first radio communication system and to receive at least second receive signals generated during operation of at least a second radio communication system, said method comprises the steps of: applying a first receive signal, if received at the multi-mode radio receiver, to a first receive chain portion (62) and a second receive signal, if received at the multi-mode radio receiver, to a second receive chain portion (64), the first receive chain portion (62) comprising a first amplifier (88) and the second receive chain portion (64) comprising a second amplifier (118); selectably acting upon the first receive signal at the first receive chain portion (62) by selectably biasing the first amplifier (88) and upon the second receive signal at the second receive chain portion (64) by selectably biasing the second amplifier (118), either one, but not both, of the first receive chain portion (62) and the second receive chain portion (64) operable during a selected period; applying a selected one of the first receive signal and the second receive signal to a common receive chain portion (66); subsequent to actions performed thereon during said operation of selectably acting; and further acting upon the selected one of the first receive signal and the second receive signal, respectively, applied to the common receive chain portion (66); further comprising the steps of: applying a third receive signal generated during operation of a third radio communication system, if received at the multi-mode radio receiver, to the second receive chain portion (64), and wherein said operation of selectably acting upon the first receive signal and the second receive signal further comprises selectably acting upon the third receive signal at the second receive chain portion (64). 40. The method of operating a multi-mode radio receiver of claim 39, wherein said operation of selectably acting upon the third receive signal further comprises selectably biasing a third amplifier (122) to allow the second receive chain portion (64) to act upon the third receive signal.
