Description
Overview
The Keysight N1811TL is a 4-port terminated bypass latching coaxial switch designed for RF and microwave applications from DC to 26.5 GHz. The switch's internal load can terminate the device under test (DUT) when in bypass mode at power levels up to 1 watt. Its compact design makes it ideal for drop-in and dropout applications where space is limited.
