Solid State 50KW AM Broadcast Transmitter

Model Number

BA-50KS

Frequency : 530~1650KHz

• Complete Solid State Using MOS-FET
• Digital Modulation Mode by A/D Converter
• Superb Combination of 128 PA Modules
• Achieved Higher Modulation Rate to 145%
• Applicable to AM Stereo

Very Low Energy Consumption

Digital Modulation Mode by both highly efficient energy saving D grade PA Amplification Modules and A/D converter, guarantees integrated efficiently over 85%. This is the major feature of the transmitter.

• Signal to Noise Rate : less than 65dB
• Distortion : less than 0.8%
• Frequency Characteristics : less than +/- 1dB

Even in failure of several units from 128 MOS-FET Modules, the unit keeps operation with shrunken transmitting capacity. To make it into normal state, it can be flexibly patched by Emergency Modules even under On-Air condition.

Many protective devices and superior protection circuits are provided for complete protection against lightning.
