RF SWITCH MODULE
SP4T Relay RF Switch Module for the RF Cogs™ Modular Series
The RFC-SW41 uses highly reliable
RF relays to implement a 4 x 1
multiplexer function. It
connects a common 75 Ohm RF port
to one of four other 75 Ohm ports.
The desired port is selected via
signals sent to the module over
an I2C bus. Each module is
individually addressable and can
be used alone or with additional
switch modules. It can also be
used with other modules in this
family which provide other
functions like programmable
attenuation or amplification.
This device has excellent high-
frequency RF characteristics,
providing very low insertion
loss and excellent isolation.
The latching-type relays
employed use a minimum of DC
power as contrasted with those
that require power to maintain
their state.
The I2C signals and DC power
connections are made thru a
multi-pin connector. There is
a second connector wired in
parallel with the first which
allows all of the modules to be
daisy-chained together from
one module to the next.
The RF connectors used on the
RFC-SW41 switch module are
F-type connectors, widely used
in cable TV and video
applications.
The modules in this series can
be mounted flat to a base plate
or vertically into an optional
3U sub-rack (standard 19 in.
rack) along with the controller
and other modules.
