Description
The SWD-119 is a quad 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.
