5W S-BAND COFDM Amplifier v1

Technical Specification

  • LDMOS technology for lower and adaptive current consumption ( 40w @37dBm )
  • Isolator for protection against high VSWR
  • Adjustable ALC (automatic level control) it is possible to adjust the output power to a desired power level that will be constant over the whole frequency range.
  • Precision lockable multi-turn potentiometer for output power adjustment
  • Wide DC input (9-36v) operating range (Motorbike 12Vdc, Helicopter 28Vdc....)
  • Reverse input polarity protection
  • 4pin XLR DC input ( 9-36Vdc )
  • 4pin XLR DC output 12Vdc 8A (max) regulated to feed transmiter DC input for example
  • Solid RF «N» (F) type input and output
  • Compact 2 RU half rack size, 19’’ racking with optional ear mounts
  • High thermal disipation for use in extremes conditions
  • Ultra low noise fans ( 31 dB )
