1 KW F.M. TV Transmitter

Model No.: TW/FM/1KW

FEATURES

Frequency- Band II 87.5 Mhz to 108 Mhz
The entire equipment, 1 KW FM Transmitter is housed in 19" Rack having 1.6 meter height and 1 meter depth. It operates from 230 V AC Mains Supply.
The 1KW FM Transmitter consists of 1 nos of Power Amplifier, 1 nos of Exciter, SMPS
FM Exciter having 80 dB Mono/stereo S/N ratio with microprocessor based synthesizer technique permitting fast frequency selection in 10 KHz steps. The exciter has built-in stereo coder for stereo transmission and can accept Radio Data service (RDS) and Subscriber Channel Authorization (SCA) inputs.
The transmitter contains MOSFET power Amplifier.
Exciter, Power Amplifier and Harmonic Filter are of wide band design.
No tuning required over the entire FM band.
Modular design for easy maintenance and parts replacements.
Complete shielding of high power RF circuits to minimize radiation.
Provision of standby Exciter having facility for Automatic change over in case of failure of Main Exciter.
Adequate metering and monitoring at modules as well as system level.
Adequate protections like DC overload, over-temperature on heat sink, over current protection for each MOSFET, high VSWR etc.
In case of higher VSWR Power folds back to 30 W.
Low noise cooling system.
In-built stereo coder, using pilot tone system conforming to CCIR Rec. 450.
Change-Over facility from mono to stereo using simple toggle switch.
High efficiency SMPS unit for Power Amplifier.
1KW power derived using six modules of 200 W output.
