SPINNER Low PIM Switches

SPINNER Low PIM Switches

There are zillions of switches out there. But when it’s about low PIM testing, the available options boil down to just a few. And if you want to use a switch in a calibrated test system and need it to keep working perfectly through hundreds of thousands of cycles without requiring any maintenance, there is really only one choice: the SPINNER low PIM switch.

The SPINNER low PIM switch—a double-pole, double-throw switch—has revolutionized equipment testing. It lets you tap potentially enormous savings on the order of about 90% compared to conventional methods. Final inspection of high-frequency products, for example, typically involves measuring their PIM, VSWR, and isolation. It’s often quite time-consuming, and therefore costly, to manually connect a variety of measurement equipment to each device under test (DUT). Our low PIM switches, in conjunction with SPINNER EasyDock test adaptors, can significantly speed up this process. It’s only necessary to hook up each DUT once, and then multiple tests can be performed quickly and easily. 

The switch is electronically operable as a relay and can therefore be integrated in automatic test processes. This makes it possible to completely test even complex products with a large number of ports in seconds instead of minutes. It also eliminates sources of error and prevents the damage that ports and cables otherwise inevitably suffer as a result of all the plugging and unplugging.

Another plus is the excellent mechanical precision of SPINNER low PIM switches and EasyDocks. This lets you smoothly integrate these components in calibrated sequential test setups. Once connected and calibrated, they enable the system to perform measurements not only fast but also very reliably and identically every time. The SPINNER low PIM switch and EasyDock are both available with 4.3-10 and 7-16 connectors. You can obtain switches either as discrete components or as a fully integrated programmable matrix.
