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.
The SWD-119 is a quad channel driver with performance
similar to the single channel version.
