  • VHF/UHF 1kW Solid-State TV TransmitterWith all-solid-state circuit design and combined transmission of video/audio carrier, convenient to upgrade to digital TV transmitter.
  • With dual professional TV exciters for optional demands and advanced RF non-linearity correction technology are able to guarantee the reliability and stability of TV signal transmitter and low transmitting signal distortion. The hot-plug power units could backup each other, ensure that there is no single fault of transmitter.
  • New type output filter (low-pass or band pass available).With adopted high-power synthesis technology, low insertion loss, high out-of-band suppression.
  • Local or remote control, friendly man-machine interface by microcomputer unit, it can display and control the operating mode of exciters, power amplifier units and transmitter, with GSM message auto alarm module, and fixed timing starting up and shutdown functions.
  • With self intellectual property rights. Develop power amplifier, power combiner, monitoring system independently.
  • Wide voltage stability range and high efficiency of power supply.
  • With over-voltage, over-current, over-heat, over-excitation, low-voltage, absent-phase, short-circuit and over-VSWR auto-protective functions; with multiple-measure of thunder-proof, it could run securely.
  • Forced-air-cooling design with low power consumption and low noise.
  • All technical specifications can meet or exceed the national and ministry standards.
