 HP/Agilent 8764B-024 DC to 18 GHz Coaxial Switch

The model 8764B is an unterminated Coaxial Switch, offering exceptional repeatability of 0.03 dB over 1 million switching cycles.  Port 5 is unterminated and can be utilized for signal path reversal or as a calibration port.

It is a 5-port switch that offers the same internal structure as the HP 8762 switches.  Elimination of the internal load makes it
possible to utilize the extra ports for a variety of purposes, such as adding external high-power loads to extend power handling
capability or reversing signal path.  The HP 8764 utilizes latching solenoids and has dc circuit interrupts to cut off solenoid current
when switching is complete.
