Systems and methods of band amplification with a shared amplifier

A multi-band bidirectional amplification wireless telecommunication system comprising:

• a first amplifier;
• a first circulator in communication with an input port of the first amplifier, wherein the input port of the first amplifier receives first and second frequency band downlink signals and first and second frequency band uplink signals;
• a second circulator in communication with an output port of the first amplifier;
• a second amplifier having an input port in communication with a third circulator and an output port in communication with a fourth circulator, wherein the input port of the second amplifier receives a third frequency band downlink signal and a third frequency band uplink signal;
• a first duplexer device in communication with the first circulator and the second circulator;
• and
• a second duplexer device in communication with the first circulator and the second circulator.

A multi-band amplification system comprising:
