Abstract
An amplifier (104) for a dual band device includes multiple amplifier stages coupled between an input (103) and output (105). The amplifier stages include a first amplifier stage (200) having a first amplifier (206), a second amplifier stage (202) having a second amplifier, and a third amplifier stage (204) having a third amplifier (210). A first bypass (218) in said first amplifier stage provides a bypass for signals in a first frequency band. A second bypass (250) is provided in the third amplifier stage, the second bypass to provide for signals in a second frequency band a signal path that bypasses the third amplifier. Signals in the first and second frequency bands are amplified by the second amplifier.
