Figure ap.n.2-1. Generic Feed Forward Circuit Schematic
Both directional couplers in the Figure ap.n.2-1 have one port terminated with a 50 Ω resistor. In order to achieve
optimum performance, the termination must be chosen carefully. It is important to remember that a good termination
will not only produce a good match at the input of the coupler, but will also maximize the isolation between the input port
and isolated port. Furthermore, since the termination can potentially absorb high levels of power, its maximum power
rating should be chosen accordingly. A list of recommended terminations is shown in Figure ap.n.2-1. For an ideal
lossless directional coupler, the power at the coupled and direct ports can be written as:
P coupled =
10
P input
Coupling ( dB )
10
Watts
Eq. ap.n.2-1
P direct = P input ?

where P input is the input power in Watts, and Coupling(dB) is the coupling value in dB.
