Description
The MADR-009443 is a four 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 V (relative to GND) to
optimize the intermodulation products of FET control
devices at low frequencies. For driving PIN diode
circuits, the outputs are nominally switched between
+5 V & -5 V. The actual driver output voltages will be
lower when driving large currents due to the
resistance of the output devices.
