Keysight 44476B Microwave relay driver module brings multi-port 50/75 ohm coaxial switching flexibility to your test system. The Keysight 44476B panel has two sets of mounting panels, so any two Keysight 876XX coaxial switches can be mounted on this module. The coaxial switches come in three-, four- and five-port configurations. This flexibility allows you to use the different switches for a variety of applications, constructing transfer switches, switch matrices and more. Using the Keysight 8762x in conjunction with the 44476B will allow you to extend your automated three-port switching to 26.5 GHz. Coaxial relays must be ordered separately. Option 011 designates the switches for a coil voltage of 5V DC.
