OVERVIEW 

The SRF series RF  passive splitters and combiners provide an economical method of splitting or 
combining a number of RF signals in ratios of 1:2,1:4,1:8 or 1:16.  They provide low insertion loss, high 
return loss, flat frequency response and high isolation between channels.  They can be used for signal 
distribution in a RF facility, or used to expand the matrix size of Evertz Microsystems XRF1 (16x16) and 
XRF6 (64x64) RF routers.

The SRF products feature RF coax connectors on both sides of the chassis for mounting on either the 
front or back of the rack for ease of installation and troubleshooting.  They also feature an input 
monitoring port for troubleshooting and diagnostics in the RF plant. 
 
The SRF1 series is housed in a 1RU frame and the SRF3 series are housed in a 3RU frame.  RF 
specifications are dependent on the split / combine ratio.  The list below includes all possible options of 
the SRF splitter / combiners.
