Keysight (Agilent) E8482A Six 1×4, 50 Ohms, 3 GHz RF Multiplexer

The Keysight E8482A is a C-size, 1-slot VXI multiplexer module designed for RF signal routing and switching in automated test systems up to 3 GHz. It houses six independent 1×4 one-wire multiplexer banks, each capable of routing one of four input channels to a common output port. Tree switching architecture delivers high isolation and low VSWR across all switching paths. All connections use SMB male connectors terminated at 50 Ohms impedance.

– Technical Specifications
