.. Single Driver for Ga As FET Switches and Attenuators Features - - - - - High Speed CMOS Technology Single Channel Positive Voltage Control Low Power Dissipation Low Cost Plastic SO-8 Package SWD-109 V5 Functional Schematic Description The SWD-109 is a single channel driver used to translate TTL control inputs into gate control voltages for Ga As FET microwave switches and attenuators. High speed analog CMOS technology is utilized to achieve low power dissipation at moderate to high speeds, enpassing 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.
