1. A remote compensator for a mobile device, the remote compensator comprising:
a first balun having a first winding and a second winding, the second winding configured to connect to an antenna;
a cable-side circulator including an output configured to provide a transmit signal and an input configured to receive an amplified receive signal;
a first phase shifter and a second phase shifter;
a first antenna-side circulator and a second antenna-side circulator;
a push-pull amplifier including an input configured to receive the transmit signal, a first output connected to a first end of the first winding of the first balun through the first antenna-side circulator and the first phase shifter, and a second output connected to a second end of the first winding of the first balun through the second phase shifter and the second antenna-side circulator; and
a receive amplifier configured to generate the amplified receive signal based on amplifying a first receive signal from the first antenna-side circulator and a second receive signal from the second antenna-side circulator.
