POWER AMPLIFIER CONTROLLER

摘要

PURPOSE:To perform an errorless radiation interference sensitivity test due to a high electric field intensity radio wave with an automatically stabilized amplification of high frequency signals by throwing-in a power source sequentially while monitoring a power source surge of a high frequency power amplifier. CONSTITUTION:A power source control section of a power amplifier controller 16 monitors a surge of a power source by a process control with a CPU 12 based on the program of a memory device 11 to stabilize the power source by control. When the stabilization of the power source is determined, source power is supplied to first to third high frequency power amplifiers 4-6 sequentially through a power source line 9 through a power source switch driver of the power source control section. An amplified output via a high frequency signal transmission path 2 of these amplifiers 4-6 is also transmitted to a corresponding antenna 8 after the determination of the stability with the device 16. This enables a stable automatic amplification of a high frequency signal thereby assuring an errorless radiation interference sensitivity test due to a high frequency radio wave.
