The LSW-203PDT from Vaunix is a USB Programmable Solid-State, Absorptive SPDT RF Switch that operates from 0.1 to 20 GHz. It has an insertion loss of less than 4 dB, over 50 dB of isolation, and an On/Off time of 14 ns. The switch has a USB Type-C interface for power and supports USB/Ethernet control interfaces. This programmable switch uses a native USB HID interface to avoid the difficulties inherent in using older serial or IEEE-488 interfaces implemented over USB. It has an easy-to-use WebUI that allows the user to configure the WebUI port and login credentials for maximum security.
The LSW-203PDT switch is easily programmable for fast switching or sequenced switching directly from the Windows Graphical User Interface (GUI) or the WebUI. Alternatively, users can develop their own interface using Vaunix’s LabVIEW drivers, Windows/Linux SDK files, Python examples, and much more. The switch is available in an enclosure that measures 101.6 x 35.6 x 21.8 mm and has SMA-female connectors. It is ideal for use in antenna switching, engineering/production test stations, and automated test equipment (ATE) applications.
