85331B 1P2T PIN switch (0.045 to 50 GHz)
85332B 1P4T PIN switch (0.045 to 50 GHz)
The 85331B and 85332B PIN switches offer the ability to switch between test channels
quickly. These high-performance PIN switches have 90 dB of isolation, low loss, and a
45 MHz to 50 GHz bandwidth. They are absorptive, providing a good impedance match,
which is key to achieving accurate measurements. The switches are small in size and
weather resistant. Figure 52 shows a typical configuration with the PIN switches
connected to the source antenna and AUT.

Note
The 85331B and 85332B do not contain a switch
control unit. If your system is configured with an
85330A multiple channel controller, the switch
control unit must be ordered separately (Agilent
part number 85331-60061).
