Microwave Switch/Attenuator Driver

The Keysight L4445A provides digital outputs to control switches, attenuators and other devices. The outputs can also be used to drive LEDs that to indicate the switch position. Digital inputs can be used to read back the actual position of the switch or attenuator. The L4445A provides power and control signals for many of the most popular microwave switches and attenuators.
