RF POWER SUPPLY DEVICE

摘要

PURPOSE: An RF(Radio Frequency) power supply device is provided to supply power to an antenna and a line amplifier of an RF band by using an antenna line. CONSTITUTION: An RF power supply channel portion(40) has the first channel(20) and the second channel(30). The first channel(20) is used for applying the power applied from an antenna line to the antenna in a normal operation. The second channel(30) is used for applying the power applied from an antenna line to a connector in a normal operation. An RF power supply portion(10) supplies the power to the RF power supply channel portion(40) when the antenna line is normally connected to the RF power supply channel portion(40). The RF power supply portion(10) stops the supply of the power to the RF power supply channel portion(40) when the antenna line is abnormally connected to the RF power supply channel portion(40). A display portion(50) displays states of the antenna line.
