Instructions to use High power amplifiers
高功率放大器使用说明
1. 为了防止静电堆积造成的损坏，电缆在连接到放大器之前应先释放静电。
2. 在向放大器提供直流电源之前先附加50欧姆的输出负载。
3. 选择功率放大器尺寸匹配的高品质散热器。
4. 将高速风扇连接到散热器的一侧；
5. 在放大器的底部加上加热化合物（如导热胶），然后将其附加到散热器上；
6. 打开风扇；
7. 将电源连接到放大器后，重复检查放大器本身的直流电压，以确保它有合适的电压给放大器供电。风扇（S）和电源可以同时打开；
8. 将射频信号应用于放大器，并开始测试放大器。不要超过测试数据中所提到的放大器的输入最大功率。
9. 持续监控放大器上的红色温度传感器。最高温度不应超过60摄氏度，如果温度传感器是黑色或达到80摄氏度，放大器可能已经被烧毁。这意味着功率放大器没有足够制冷的冷却系统。
强烈建议：
要配置一个非常好的和大的散热片和高速吹风扇，放大器上的温度应小于40摄氏度；
强烈建议在放大器的顶部添加第二个较小的散热片，使放大器冷却效果更好。
1. To prevent damage through static charge build up, cables should be always discharged before connecting them to the amplifier.
2. Attach a 50 ohm output load before supplying DC power to the amplifier.
3. Select a high quality heatsink with the right dimensions for the power amplifier.
4. Attach fast blowing fan(s) to one side of the heatsink.
5. Add heating compound at the bottom of the amplifier before attaching it to the heatsink.
6. Check the right DC voltage on the power supply before connecting it to the amplifier. Make sure the power supply has enough current to be used with the amplifier.
7. Turn on the fan(s)
8. After connecting the power supply to the amplifier, double check the DC voltage on the amplifier itself to make sure it has the right voltage to power the amplifier. Fan(s) and power supply can be turned on simultaneously.
9. Apply RF signal to the amplifier and start testing the amplifier. Do not exceed the input maximum power of the amplifier mentioned on the test data.
10. Keep monitoring the red temperature sensor on the amplifier. The maximum temperature should not exceed 60 degree C. If the temperature sensor is all black or reaches 80‐85 degree C, the amplifier may already be burned. Which means the power amplifier doesn’t have adequate cooling system.
With a very good and large heatsink and fast blowing fan(s), the temperature on the amplifier should be less than 40 Degree C
Note: It is highly recommended to add a second smaller heatsink on the top of the amplifier to make the amplifier run cooler.
