Pin diode switch driver.

Microsemi s switch drivers contain internal spiking and decoupling capacitors. Driver circuits for high power pin diode switches the information in this chapter is presented as a guide for the rf switch switch driver interface. The bias circuit typically uses a low pass filter between the rf circuit and the switch driver. Inputs are compatible with standard logic families.
