Abstract
An amplification circuit that enables a network amplifier to amplify multiple mobile telephone signals transmitted at different frequencies. The amplification circuit includes a first diplexer which receives a first signal having a first frequency band and a second signal having a second frequency band. The first diplexer generates a combined signal containing both the first and the second signals. The combined signal is amplified by a single low noise amplifier to generate an amplified combined signal. A second diplexer receives the amplified combined signal and separates the amplified combined signal into a first amplified signal having the first frequency band and a second amplified signal having the second frequency band. The resultant signals can then be transmitted by the network amplifier to a target destination, such as a handset or base station.
