CEKE 50W MMDS TV Transmitter Outdoor Type
CKMB-50
Product Introduction
A. Optimized products indicators, meet the requirement of Wide Frequency Band transmission,
reduce investment,save energy to decrease operation cost.
C. Compatible for 4 different Wide Frequency Band transmission standard : ATSC (USA) / DVB
Main Features
1) Low power consumption and linearization design improves transmitting power and reduces nonlinear distortion products.
2) Very low local oscillator phase noise and group delay are compatible with analog and digital signal transmission.
3) ALC keeps constant power output.
4) 10MHz built-in precise reference source realizes precise frequency phase lock control(optional).
5) Outdoor design improves the effective transmission power and reduces transmitting feeder costs. The roof structure case especially suit for southern rain thermal environment.
6) Local condition monitoring and control.
7) Wireless remote condition monitoring and control(optional).
