Features:

  • Compatible with digital and analog transmitter
  • Apply to PAL G/I/D/K adjacent or nonadjacent-channel combine
  • Every channel with 8MHz bandwidth and independent structure. Can be stack mounted as many as 23 channels available
  • TV transmitting signal in multi-channels only need a set of antenna-feeder system to lower the cost of system
  • Aluminum weld structure with firm joint and low insertion loss

Features:

  • Considered various application environment and conditions, and the device is designed with high reliability to realize all-weathers and unattended and nobody monitor.
  • With high-power broad frequency band synthesis technology, adopted LDMOS high-power FET of power amplifier module, the devices redundancy is high. Nonlinear feed correction technology, make the device extremely high linear and reliable.
  • ALC circuit guarantees power output stable, which ensures the stability, reliability and excellent performance of device.
  • Intelligentized controlling and remote monitoring functions, could configure and monitor equipment parameters through RS-232 interface support SNMP protocol optional. With GSM message autoalarm module, and fixed timing starting up and shutdown functions.
  • Casting aluminum alloy body, with outdoor style, windproof, rainproof and lightning proof functions.
  • Alarming and monitoring functions, which could be displayed by LED in front panel.
  • 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.

 

Features:

  • 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.
