Quick Bias-T for ebay LNA

This is a quick hack to power a cheap chinese LNA from the coax. This is only intended to work in UHF band.

  • Inductor : 4310LC Wideband Bias Chokes from coilcraft
  • 10uF tantalum capacitors
  • 0.1uF ceramic capacitors
  • 5v LDO (high quality low noise would be better)
