Digital MMDS Transmitter

Digital MMDS Transmitter
Product Detailed
Digital MMDS Transmitter: 1. linearity design of low power dissipation 2. low local oscillation phase noise

Digital MMDS Transmitter for Headend

Description

1. Low local oscillation phase noise enhances the digital signal transmitting quality,2.A linearity design of low power dissipation promotes the power of transmitter and reduces the non-linearity distortion products3. Outdoor design promotes valid transmitting power and reduces the cost of transmitting feeder loss4. outdoor design greatly reduces the system cost by eliminating the waveguide5. small-size design fits he project6. Self-cooling heat sink increases the device reliability7. Aluminum structure design facilitates the maintenance.
