44476A Microwave Switch Module

The 44476A contains three Microwave Switches. These switches have
the following features:
Broad bandwidth (dc to 18 GHz)
High isolation (> 90 dB to 18 GHz)
Excellent repeatability (typically 0.03 dB after 1,000,000 switchings)
Internal 50 Ω terminations
The Agilent 8762B is a break-before-make switch controlled by a
latching solenoid. Once switched, coil voltage can be removed and the
switch remains in the switched position. Internal coil contacts open and
remove coil voltage after a switching operation to minimize the amount
of heat dissipated near the switch contacts. The Agilent 8762B uses SMA
connectors for ease in cable connections
The 3499A/B/C identifies this module as a 44471A on the front-panel
display. Changing the state of channels other than channels 00 through
02 does not generate an error, but has no effect.
Specifications for the 44476A are given on page 344.
