  Power Dividers
 
Spectrum Microwave Power Dividers are designed with attention to high isolation and exceptional phase balance. These Wilkinson style Power Dividers rely on quarter-wave transformers matching the split ports to the common port yielding superior isolation between the output ports, while maintaining a matched condition on all ports. These printed circuit board Power Dividers are a low cost solution, for stripline and microstrip styles can be produce without the high cost of lumped inductors or capacitive elements.
Wilkinson Style Power Dividers
  • High isolation
  • Excellent Phase Balance
  • Extremely Low Loss
  • Excellent Amplitude Tracking
  • Cost Effective
  • Designed to meet MIL-E-5400 Class 3

* Input power with 1.5 max. output system VSWR. Power handling is reduced when used as a combiner, measured @ 1 GHz. (Consult factory if needed)
^ To equalize the phase at all three ports, add an additional external line length to J3 equivalent to a 9 mm air line.
~To equalize the phase at all four ports, add an additional external line length to J3 and J4 equivalent to 3.5 cm of air line each.
** Specifications noted are midband at 25°C, please consult datasheet for specific guaranteed performance parameters over temperature.
