Amplifier arrangement with time constant control
First Claim
1. An amplifier arrangement for a signal receiver, the arrangement including an amplifier, a first switching means arranged to alter the time constant of the amplifier in dependence upon the signal frequency of the signals applied to the amplifier, and a balancing means arranged to prevent transient signals produced by the switching means from affecting the performance of the amplifier.

Abstract
An amplifier arrangement suitable for use in a receiver for use in a telecommunications system is described. The arrangement includes an amplifier and an FET switch arrangement arranged to alter the time constant of the amplifier in dependence upon the incident signal frequency. A balance switch arrangement is arranged such that switching transients of the switch arrangement are cancelled out in the amplifier arrangement.
