Circulator in RF system, why should engineers care?

When implementing a transmitting and receiving system, the first question that engineers have to solve is: how to prevent the high-power signal from the transmitter from bouncing back and damaging the receiver, while both have to use the same antenna? At first glance, many people think that they can install two separate antennas or use a switch. In fact, the cost, latency and complexity will increase a lot. This is the reason why the signal transmitter is used, because it solves both technical and economic problems.
