RECEIVER AND AUTOMATIC GAIN CONTROL METHOD THEREOF

Title:

RECEIVER AND AUTOMATIC GAIN CONTROL METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2004/021564

Kind Code:

A1

Abstract:

A receiver can easily set a stable amplifier output gradient. The output from an active filter to an intermediate frequency amplifier is detected by a second detector and AGC of a high frequency amplifier is performed. By separating the AGC feedback loop for the intermediate frequency amplifier (4) from the feedback loop for the high frequency amplifier, it is possible to easily set output gradients of the stable high frequency amplifier and the intermediate frequency amplifier.
