Keysight Technologies (formerly Agilent) N1811TL-004-115-202 is a four-port coaxial RF switch configured as a bypass, terminated, latching device that operates from DC to 4 GHz. It uses a 15 VDC coil drive (Option 115) to set and retain its state and provides solder-lug terminations (Option 202) for RF connections. This configuration is designed for RF/microwave manufacturing test systems, enabling repeatable signal routing up to 4 GHz in a compact four-port package for production-line and bench testing.
