SCRF Series Splitters and Combiners
1. OVERVIEW
The SCRF series radio frequency ( 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 or 1:8. 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 ) L band routers.
Figure 1: Front View of SCRF3-64-1x2 chassis
Figure 2: Rear View of SCRF3-64-1x2 chassis
The SCRF 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 SCRF1 series is housed in a 1RU frame and the SCRF3 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 SCRF splitter / combiners.
SCRF1 SERIES:
SCRF1-16-1x2 16-channel 1x2 splitter / 2x1 combiner
SCRF1-8-1x4 8-channel 1x4 splitter / 4x1 combiner
SCRF1-4-1x8 4-channel 1x8 splitter / 8x1 combiner
SCRF3 SERIES:
SCRF3-64-1x2 64-channel 1x2 splitter / 2x1 combiner
SCRF3-32-1x4 32-channel 1x4 splitter / 4x1 combiner
SCRF3-16-1x8 16-channel 1x8 splitter / 8x1 combiner

1.2. TYPICAL APPLICATION DIAGRAM
Figure 1 illustrates the use of four SCRF3-64-1x2 modules to achieve a 128x128 router using four XRF6 L
band routers. On the input side, the SCRF functions as a splitter and as a combiner on the output side,
allowing non-blocking routing of any input to all outputs.

2. INSTALLATION
The SCRF splitters and combiners have RF coaxial connectors on the front and back side of the chassis.
The input ( common ) and monitoring ports are on the front of the panel. Output connectors are located on
the rear side of the chassis.
The monitoring port can be used for diagnostics and monitoring. This port is a –20dB tap of the common
port. Terminate this port with a 75 Ohm load when not connected.
"
Please note all unused outputs on a channel ( including monitoring outputs ) must be
terminated with a 75 Ohm load if they are not connected. Please contact Evertz
Microsystems for recommended termination suppliers.
