34946A/47A—from DC to 26.5 GHz
For applications where you need only a few high-frequency switches, the 34946A and 34947A offer ingle-
pole, double-throw switches in either 4GHz, 20GHz or 26.5GHz options. These modules internally mount
two or three independent Keysight N1810 series coaxial switches. These switches are well known for
their excellent insertion loss, isolation and VSWR specifications.
Switch read back capabilities allow you to query the position of the switch. You can choose higher density
with the unterminated switches or select the terminated switches to maintain impedance match.
34946A/47A option 001
These modules can also be ordered without switches installed. This give you the capability to install your
own N1810 series switches or use the module to control the N1810 Series switches outside the
mainframe.
