2000W Digital TV Transmitter

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 6-8MHZ.

●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.
