Directional Coupler Characteristics.
The main disadvantage of the two hole directional coupler is
In a directional coupler
Where is the resistive load placed in a directional coupler?
For coupled line coupler, if the voltage coupling factor is 0.1 and the characteristic impedance of the microstrip line is 50 Ω, even mode characteristic impedance is-
Coupling factor of a directional coupler must be maximum and is a key factor that determines the performance of the coupler.
