Digital MMDS Transmitter
Product Detailed
Digital MMDS Transmitter: 1. linearity design of low power dissipation 2. small-size design fits he project

Digital MMDS Transmitter

Description:

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 productsOutdoor design promotes valid transmitting power and reduces the cost of transmitting feeder lossoutdoor design greatly reduces the system cost by eliminating the waveguidesmall-size design fits he projectSelf-cooling heat sink increases the device reliabilityAluminum structure design facilitates the maintenance.
