NPA 300
FM
Broadband Amplifiers 87.5 - 108 MHz
- Very high efficiency Mosfet technology amplifier
- High gain PA, typically capable of 270W output power
with 10W drive input power
- Automatic gain control providing fixed output power
even in case of fluctuating drive power (2% tolerance)
- High reliability, and consistent performance achieved
due to total absence of tuning requirements
- VSWR proportional auto-foldback, excessive temperature
and excessive drive power protection, with indicator lights, put the transmitter driver in
stand-by mode after recycling.
- Conservatively designed compact high-efficiency
switching power supply modules provide easy access and overall AC to RF efficiency of
better than 64%.
- Meets or exceeds all FCC and CCIR requirements
- Easily replaceable standard components
- Full remote control and telemetry capability, with all
main parameters on rear panel DB-25 connector.
