Abstract:
An amplifier, comprising:an input port for receiving an input signal comprising a radio frequency (RF) component and an alternating current (AC) power component;a first filter coupled to the input port for filtering the AC power component from the input signal and for providing the RF component, in the form of an RF signal, at its output;a second filter coupled to the input port for filtering the RF component from the input signal and for providing the AC power component, in the form of a power signal, at its output;amplification circuitry coupled to the output of the first filter for amplifying the RF signal to generate an amplified RF signal;a first output port coupled to an output of the amplification circuitry and to the output of the second filter for transmitting a first output signal comprising the power signal and the amplified RF signal;a second output port; anda plug-in splitter that is removably coupled to the amplifier, wherein, when the plug-in splitter is coupled to the amplifier, the plug-in splitter receives the RF signal and the power signal from the first and second filters, respectively, couples the RF signal from the first filter to the amplification circuitry, couples the power signal from the second filter to the first output port, and also couples the RF signal and the power signal from the first and second filters, respectively, to the second output port, which provides a second output signal comprising the RF signal and the power signal.
