NA300, 300 kW AM TRANSMITTER

Product Information

Fast frequency change design permits field tuning to any frequency in the MW band
125% positive peak modulation at 300 kW
1.5:1 VSWRat 300 kW, 100% modulation
Forty load sharing, hot-pluggable power modules
Broadband, plug-in RF amplifiers
Dual RF exciters and modulation encoders with automatic changeover

Synthesized exciter uses advanced DDS technology to produce RF drive at the desired operating frequency. For synchronous operation an external input is provided for a 10 MHz precision GPS reference clock.
Fully compatible with DRM digital radio broadcasting
High overall efficiency (85% to 88% typical) results in low power consumption (529 kW typical at 300 kW, 100% modulation) and reduced operating costs
