Single Driver for GaAs FET Switches and Attenuators Features • • • • • SWD-109 V5 Functional Schematic High Speed CMOS Technology Single Channel Positive Voltage Control Low Power Dissipation Low Cost Plastic SO-8 Package 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.

All voltages are relative to GND. 2. VOPT is grounded for most applications. To improve the intermodulation performance and the 1 dB compression point of GaAs control devices at low frequencies, VOPT can be increased to between 1.0 and 2.0V. The nonlinear characteristics of the GaAs control devices will approximate performance at 500 MHz. It should be noted that the control current is on the GaAs MMICs will increase when positive controls are applied.
