The 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 to +2.0V (relative to GND) to optimize the intermodulation products of the control devices at low frequencies. The is a quad channel driver with performance similar to the single channel version.

All voltages are referenced to GND. All inputs and outputs incorporate latch-up protection structures.

Single/Quad Drivers for GaAs FET Switches and Attenuators Guaranteed Operating Ranges

Parameter 1 Positive DC Supply Voltage Negative DC Supply Voltage Optional DC Output Supply Voltage Negative Supply Voltage Range Positive to negative Supply Range Operating Ambient temperature DC Output Current - High DC Output Current - Low Maximum Input Rise or Fall Time

1. 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.
