 Low local oscillation phase noise enhances the digital signal transmitting quality.
 A linearity design of low power dissipation promotes the power of transmitter and reduces the non-linearity distortion products. 
 Outdoor design promotes valid transmitting power and reduces the cost of transmitting feeder loss.
 Outdoor design greatly reduces the system cost by eliminating the waveguide.
 Aluminum structure design facilitates the maintenance and power update.  
 Small-sized design fits the project
