The Agilent 34946A microwave switch for the 34980A Multifunction Switch/Measure Unit offers bi-directional switching for test signals from DC to 20 GHz. These switches provide excellent insertion loss, isolation, and VSWR specification. The microwave switches are configured as two independent 1×2 (SPDT) terminated switches on a single module. For general-purpose microwave switching applications, the module can be used to switch separate signal sources for a multi-band receiver/transmitter testing application.
