1. A system for testing a power durability of a surface acoustic wave (SAW) filter, comprising:

  • a signal generator for generating a continuous wave of an oscillator;

    a high power amplifier for amplifying a signal applied from the signal generator into a target power level;

    a power durability tester (PDT) for receiving the amplified signal from the high power amplifier and monitoring a power applied to a SAW filter, and setting a path for monitoring an electrical property through a network analyzer;

    a power meter for measuring an output signal of the PDT;

    a controller for changing a path to monitor an electric property of the PDT;

    the network analyzer for analyzing an electrical property of the SAW filter;

    a reliability tester for applying a test temperature to the SAW filter and maintaining the applied test temperature;

    a thermal meter for measuring a temperature of the SAW filter;

    a temperature controller for controlling a test temperature applied to the reliability tester; and

    a computer for controlling the signal generator, the power meter, the network analyzer, the controller, the temperature controller, and the thermal meter.
