Agilent/Keysight U7104N

The Agilent/Keysight U7104N is a Single-Pole, Four-Throw (SP4T) electromechanical switch for high-frequency signal routing from DC to 54 GHz. It routes one input to any of four outputs with high repeatability and minimal signal degradation. The device employs opto-electronic current interrupts to open unselected ports while simultaneously closing the selected path and terminating inactive ports with 50-ohm loads. This architecture eliminates solenoid current draw during steady-state operation, reducing power consumption and thermal effects.
