MOBILE COMMUNICATION RELAY SYSTEM, TOWER TOP AMPLIFIER AND HIGH POWER AMPLIFIER

摘要

PURPOSE: A mobile radio communications relay system using a high power amplifier compensating power supply is provided to supply a uniform mobile communication service in a tower top amplifier. CONSTITUTION: A mobile relay system includes a BS(Base Station)(10), a line(30), a tower top amplifier(40) and an antenna. The line transfers the signal transmitted from the base station. The tower top amplifier is connected to the line. The tower top amplifier receives a message signal. The tower top amplifier recompenses the electricity of being lost in the line. The antenna is connected to the tower top amplifier.
