Notes:

  • Power dissipation includes all three internal boards with all outputs terminated into 50 Ω. Each 1:10 board draws 725 mA maximum. The 1:4 board is powered internally from the bottom 1:10 board and draws 350 mA maximum.
  • fMAX should not exceed 125 MHz, otherwise damage of the unit due to overheating may result.
  • fMAX2 is measured by driving a PRL-414B at the end of a 100 ft cable.
