17.4.3.5. Wideband Asymmetric Coupler (07-015102)
The purpose of Wideband Asymmetric Coupler (07-015102) is to tap off a known portion (in this case
10dB) of RF signal from transmission lines and to combine them, for example through splitter units for
different purposes (alarms/monitoring etc.), whilst maintaining an accurate 50Ω load to all
ports/interfaces throughout the specified frequency range. They are known formally as directional
couplers as they couple power from the RF mainline in one direction only.
