Dual 1x2 SPDT Terminated Microwave Switch Module f. 34980A, w/ option: 020 = 2x N1810TL 20GHz Terminated Switches The Agilent (now Keysight) 34946A is a microwave switch for the 34980A multifunction switch/measure unit offers bi-directional switching for test signals from DC to 26.5 GHz. This switch provide excellent insertion loss, isolation, and VSWR specification. The microwave switch is configured as two independent 1x2 (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. Two SPDT terminated switches 4 GHz , 20 GHz or 26.6 GHz options (This unit has the 20 GHz option) High isolation, low VSWR Up to 50 W switching SMA connectors External switch mounting option
