Description

The SWD-109 is a single channel driver used to

translate TTL control inputs into gate control

voltages for GaAs FET microwave switches and

attenuators. High speed analog CMOS technology

is utilized to achieve low power dissipation at

moderate to high speeds, encompassing most

microwave switching applications. The output HIGH

level is optionally 0 to +2.0V (relative to GND) to

optimize the intermodulation products of the control

devices at low frequencies.
