$1.($Pozar$,\backslash (4^\{\backslash$text $\{$th $\}\}\backslash )$ ed$,$ Problem $7\mathrm{.}2[$Modified$])$ An input RF signal of $1$ W is connected to the input port of a directional coupler. The coupler has the following properties:

Coupling factor $($C$)$: $20$ dB

Directivity $($D$)$: $35$ dB

Insertion loss $($IL$)$: $1$ dB

Find the output RF power at all $3$ remining ports. Assume all ports are matched.
