Abstract
An amplifier (600) includes a first terminal (605) for receiving forward signals in a first frequency band and a second terminal (655) for receiving reverse signals in a second frequency band. A single gain block (630) is coupled between the first terminal (605) and the second terminal (655) for amplifying the forward signals and the reverse signals. The forward signals, after amplification, are provided to the second terminal (655) for transmission from the amplifier (600), and the reverse signals, after amplification, are provided to the first terminal (605) for transmission from the amplifier (600). In this manner, both forward and reverse signals, which are transmitted in separate frequency bands, can be amplified by a single gain block (630).
