NA 300/500/1000

FM Broadband Mosfet Amplifiers 87.5 - 108 MHz Range

• Extremely high efficiency Mosfet technology amplifier.
• High gain PA, typically capable of more than 1000W (NA1000/M) output power with 20W drive input power, 500W (NA500/M) output power with only 10-15W drive input power, 300W (NA300/M) with 10W of input power.
• Automatic gain control providing fixed output power even in case of fluctuating drive power
• High reliability, easy handling and consistent performance standard achieved among the various units due to total absence of tuning requirements
• VSWR, excessive temperature and excessive drive power protection, with indicator lights, which will put the transmitter driver in stand-by position in the event of failure
• Compact size with built-in high-efficiency switching power supply, providing easy access and an overload reset system with indicator lights
• Meets or exceeds all FCC and CCIR requirements
• Easily replaceable standard components
• Advanced recycling overload and protection system that provides automatic restart after about 90 seconds of stand-by in case of fault. This procedure is repeated four times and in case of persisting fault, the cycle re-starts again after 15 minutes, for four more times. If fault still persists, the stop becomes permanent. If instead, during one of the re-starts the fault disappears, the counting circuit system is reset after a regular working period of 15 minutes.
• Full remote control and telemetry capability, with all main parameters on rear terminal board
