2IF output frequency: 600~800Mhz.
3Light-wave length:1300~1600.
Outline
1:Low local oscillation phase noise, enhancing the digital signal transmitting quality
2:A linearity design of low power which promotes the power of transmitter and reduces the non-linearity distortion products
3:Outdoor design promotes effective transmitting power and reduces the feeder loss. The design also saves the 4:wave-guide, which greatly reduce the cost of system.
5:Small design for project construction
6:Self-cooling heat design increases the reliability of equipment
7:Aluminum structure facilitates the maintenance
