RVR PJ500MC Solid State Amplifier (63090)

Product features

• Exceptionally high gain P.A. with relatively low input.
• 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.
• Very high efficiency of P.A., typically capable of more than 500 W output power with about 8 W of drive input power.
• Composed of two parallel 300 W R.F. power amplifier modules for highest reliability.
• These modules are coupled through a Wilkinson Splitter and Combiner realized
  with "Strip-Line Technology".
• Protection for internal and antenna VSWR, excessive temperature and excessive drive power, with indicator lights, which will put the transmitter driver in stand-by position in the event of failure.
• Features a protection that in case of overcurrent on one 300 W P.A. Module reduces the voltage on the drain of the pair of 300 W modules interesting in faulty; then, this protection card check the status of each single R.F. Power Amplifier module's protection fuse.
• High efficiency switching power supply.
• Compact size dimensions with built in power supply.
• Easily replaceable standard components.
• Advanced recycling overload and protection system that provides automatic re-start after about 10 seconds of stand-by in case of fault. This procedure is repeated four times and in case of persisting fault, the cycle restarts again after 90 seconds, 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 resetted after a regular working period of 90 seconds.
• If one or more power amplifier modules fails (totally or partially) the amplifier automatically reduces output power to a safe value but continues transmitting.
• Terminals Strip for telemetry and remote control.
