The antenna port feed to the T/R channel usually passes through a ferrite circulator, often with a ferrite isolator to protect the power amplifier, or occasionally with a high power T/R switch that can terminate the receive path with a load during the transmit pulse cycle.
Another example is a ferrite circulator, where even modest heating can bring the ferrite above the Curie temperature and disable it.
