HP 34905A 2 GHz Dual 1:4 RF Mux, 50 ohm

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP 34905A RF multiplexer offers broadband switching capabilities for high-frequency and pulsed signals. Use it to route test signals between your device under test and your signal generator, oscilloscope, spectrum analyzer, or other instrumentation.

The RF multiplexers are arranged as two independent 1x4 multiplexers, each with a common shield and a switched center conductor. Connections can be made directly to SMB inputs with 2 GHz usable bandwidth, or to the BNC-to-SMB adapters provided with 1 GHz bandwidth. Multiple banks may be cascaded together for applications requiring even larger topologies--create a stubless 16:1 multiplexer in a single frame.

Module Specifications

Up to three modules, in any
combination, can be inserted into a single mainframe. The HP 34970A's
internal DMM connections are accessible only through the HP
34901A, HP 34902A, and HP 34908A low-frequency multiplexers.
The HP 34905A and HP 34906A RF Multiplexers use SMB connectors.
A standard set of (10) BNC-to-SMB adapter cables is provided with
each RF module for convenient BNC connections.
