This product has excellent performance indicators, the designed power redundancy is large, and uses high-power field effect transistors (LDMOS) suitable for digital TV signal amplification as power amplifier components. The power supply and power amplifier components are all hot-swappable devices. The one-time combined power combiner developed by our company has the characteristics of low loss and low standing wave, and is especially suitable for use in all solid-state digital TV transmitters. This product has unique and complete multiple detection and protection functions. The power amplifier component has real-time display of amplifier working parameters and protection functions such as overcurrent, overtemperature, and overpower.


Features:
All solid-state digital TV transmitter, bandwidth is 30MHZ.
Pre-distortion correction, dual-exciters switch automatically.
High Linearity LDMOS Power Amplifier, high-gain power amplifier module, parallel switching power supply, it is a high-efficiency transmitter.
Telemetry and remote control by computer, web-based interface and software.
Good man-machine interface, full automatic switch the machine with one key.
Multi protection (over voltage, over current, overheating, large standing-wave ratio ...)high reliability, 24 hours continuous works.
