2.Low local oscillation phase noise
Outline
Low local oscillation phase noise, enhancing the digital signal transmitting quality
A linearity design of low power which promotes the power of transmitter and reduces the non-linearity distortion products.
Outdoor design promotes effective transmitting power and reduces the feeder loss. The design also saves the wave-guide, which greatly reduce the cost of system.
Small design for project construction
Self-cooling heat design increases the reliability of equipment
Aluminum structure facilitates the maintenance
