The Agilent/Keysight L4433A is a 2-port RF multiplexer that routes one of two RF inputs to a single output with high fidelity. Designed for automated test systems, it delivers low insertion loss, excellent return loss, and high port-to-port isolation across a wide frequency span. The module integrates directly into LXI and VXI instrumentation chassis, enabling rapid signal switching and programmatic control in demanding RF test environments.
