Product Description
Characteristics
1. 1000MHz bandwidth design.
2.The pre-amp of forward path adopts GaAs MMIC amplify module, output stage
adopts the latest imported, high index, power doubler module, achieve the high
output level, low distortion and high signal to noise ratio.
3. It is more convenient to debug because of the plug-in duplex filter, equalizer,
attenuator, output splitter and the scientific and reasonable on-line detection ports.
4.The equipment can long time continuous work steadily under outdoor bad
environmental condition. Because of the aluminum waterproof housing, high
reliability switching power supply and strict lightning protection system.
