| Abstract: |
| A PIN diode switch driving circuit is presented. The control signal is i
solated with the high voltage source in this circuit. It can work at 300V and ha
s 800mA current drive capability. The switching time is below 2.6 μs. The circu
it
′s working stability is improved greatly through anti-breakdown protection and
adding appropriate time-delay circuit. This circuit can be used in high-voltage,
hi
gh-current, high-power-capacity and high-speed PIN switch. |
