------Question for FM71S9016 Please Put your question below------

I recently purchased the above listed switch. One of my selection criteria was that the switch was absorptive, which the switch is listed as being. However, upon measurement with a VNA it seems that the switch is reflecting from the unused port. I am wondering if there is a more surefire way to check the switch or if this measurement is enough.

Greetings,

I’m not finding anything in the manufacturer’s documentation to indicate whether the device is designed as reflective or absorptive type. One’s well advised to presume reflective at least for mechanical devices, so I’d trust your measurements and and consider the listing to be incorrect.
