Abstract :
High-speed T/R converter is developed in this paper by using the combination of the circulator, the limiter and the RF switch technology. The super low noise receiving technology is realized through reducing the transmission loss and improving the gain of LNA. Experiments have proved that the T/R component´s power tolerance in this paper is more than 100 W, and that the blind distance caused by it is less than 800 meters.
