Information
General description: The TRANSMITTER TV 300W p.s. VHF model "ETV300V" is built with LDMOS technology. It is composed of an A.M. Modulator, an IF/CH TV Converter (DRIVER) and an 300W peak sync. AMPLIFIER. This TRANSMITTER is used for transmitting Analog TV signal, ensuring high efficiency and excellent linearity for all VHF Band. Synthesized AM Modulator PAL of NTSC System Driver TV IF/CH Converter (RF out 5W Peak Sync.) with OL low Noise (programmable Channel). AGC and ALC Control with Peak Detector Combined Carrier wideband solid state Amplifiers (LDMOS Tech.) Display Multi-function on all DEVICE. Switching Power Supply with PFC Modular and compact construction with 19"RACK Cabinet LOW POWER Consumption Maintenance Free Notch Band-Pass Cavity FILTER (optional)
