-
In the given figure shows the equivalent circuit of a magic tee. If all ports are matched
-
Assertion (A): Microstrip is very commonly used in microwave integrated circuits.
Reason (R): Microstrip has an easy access to the top-surface so that active and passive discrete components can be easily mounted.
