4.5.5.5. 30dB Bi-Directional Coupler (07-022005)
The purpose of these couplers is to tap off known portions (in this case 30dB) of RF signal from
transmission lines and to combine them, for example though splitter units for different purposes
(alarms/monitoring etc.), whilst maintaining an accurate 50: load to all ports/interfaces throughout the
specified frequency range. 07-022005 is a Bi-Directional device and as such will couple 30dB of
signal whichever direction the signal is traveling.
