Abstract
A low-power voltage and low-power current driver for use with PIN diode phase shifters is disclosed. The driver uses transistors which function as emitter followers for rapid switching of the voltage applied to the PIN diode and as a voltage or current source for the diode bias. The driver provides for separate control of the reverse bias voltage and forward bias current applied to the PIN diode.
