Abstract
An amplifier (100) for amplifying signals includes a diplex filter (120) having a highpass filter (110) and a lowpass filter (115), and an amplifier circuit (205) for amplifying higher frequency signals provided by the highpass filter (110) of the diplex filter (120). Because the highpass filter (110) introduces attenuation of the higher frequency signals within a particular frequency range, the amplifier (100) also includes a gain control circuit (155) coupled to the amplifier circuit (205) for adjusting the gain of the particular frequency range. Both the diplex filter (120) and the gain control circuit (155) can reside in a plug-in module that can be inserted into and removed from the amplifier (100).
