ISSUE 10.3 JUN 2021
Supported by
eBIRST
The 50 Ω version of the 40-725 is supported by eBIRST
switching system test tools. These simplify switching
system fault-finding by quickly testing the system and
graphically identifying the faulty relay.

The 40-725 is an 8x9 RF matrix module suitable for
switching frequencies up to 500 MHz. Available in either
50 Ω or 75 Ω versions with SMB coaxial connectors, it is
intended for the easy construction of high performance
bidirectional matrix switching systems.
Automatic isolation switches are located on all X and
Y connections (see diagram below). These can be used
to disconnect the matrix from the external test fixture,
maximizing isolation and RF performance.
