VDC 50/600 Ohm Low Power Wide Band Measuring Transformers

VDC

  • Wide band operation models for
    • 20Hz - 20KHz
    • 100Hz - 200KHz
    • 50KHz - 10Mhz
    • 1.5 MHz to 32 MHz
  • 1 Watt Average
  • 2 Watts PEP
  • Fully encapsulated

The Minns Baluns VDC Series are designed for precision measurement purposes where 50/600 Ohm transformation is required with low VSWR and high balance ratio.

All the measuring transformers are fully encapsulated within a cast aluminium case to provide a high stability product capable of withstanding the most severe environment.
