High Gain Microwave Frequency Shift Repeater for Remote LTE/EGSM Signal Coverage Extension in Rural Areas

ATNJ Frequency Shifting Repeater is designed for mobile signal coverage extension in long-distance outdoor applications using microwave technology. The system consists of a Master Unit (MU) and a Remote Unit (RU). The MU shifts signals from working channels to unused channels at different frequencies and transmits them to the RU. The RU shifts the received signals back to their original frequencies, amplifies them, and transmits to the coverage area. With frequency shifting technology, 360° coverage can be achieved, completely eliminating isolation problems.

Operating Principle of the RF/Microwave Frequency-Converting Near-End Unit (MU+RU) in a Microwave Frequency-Shifting Repeater System. The MU consists of a MU radio frequency unit, a near-end microwave RU, and a microwave antenna. The microwave unit and the RF unit are connected with a coaxial cable. The power supply mode of the microwave unit is coaxial cable feeding.
