Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] figure 1 is a block diagram of a power amplifier aging device according to the present invention. Such as figure 1 As shown, the power amplifier aging device of the present invention includes: an off-line calibration unit 102 (PC test software), which is used to adjust the quiescent current and gain of the power amplifier so that the gain is basically consistent. The heat exchange unit 104 is used to ensure that the temperature in the power amplifier aging device is constant. The monitoring and signal generating unit 106 is used to control the power amplifier and the heat exchange unit, and provide input signals to the power amplifier. The power amplifier connection unit 108 is used to realize the connection between the power amplifier and the monitoring and signal generating unit, which facilitates the operation of wiri...

Abstract

The invention provides a power amplifier aging device and a method thereof. The power amplifier aging device comprises an off-line calibrating unit, a heat exchange unit, a monitoring and signal generating unit, a power amplifier connecting unit and a background monitoring unit, wherein the off-line calibrating unit is used for adjusting the static current and plus of a power amplifier; the heat exchange unit is used for ensuring the constant temperature in the power amplifier aging device; the monitoring and signal generating unit is used for controlling the power amplifier and the heat exchange unit and providing signals for the power amplifier; the power amplifier connecting unit is used for realizing the switching of the power amplifier and the monitoring and signal generating unit; and the background monitoring unit is used for collocating basic parameters for aging and monitoring the monitoring and signal generating unit. The invention is suitable for the aging and filtrating of the power amplifier of a base station system, and can stabilize the characteristics of the power amplifier and filtrate the early failure of the power amplifier without building an aging house.

Description

technical field [0001] The invention relates to the field of power amplifiers, in particular to a power amplifier aging device and method. Background technique [0002] The traditional aging of electronic equipment is to put the electronic equipment in a high-temperature room for power-on aging. The same method is used for the aging of the power amplifier. The disadvantage of this method is that a special high-temperature room needs to be built, and it is very cumbersome to load the power amplifier. Time to turn off the high temperature room, the use efficiency of the aging room is relatively low. [0003] Usually, there is another method in the industry, which is to age the power amplifier in a normal temperature or high temperature room without loading. This aging will be slightly less efficient. Contents of the invention [0004] Aiming at one or more of the above problems, the present invention provides a power amplifier aging device and method, which are suitable f...
