1. super high power, low noise radio frequency receiving front-end module, it is characterized in that the ANT-TX passage adopts the high-power PIN diode of a low series resistance, low thermal resistance as switch element, the ANT-RX passage adopts two little electric capacity, and the middle power P IN diode of low series resistance is as switch element;

  • The switching circuit of Zhi Zuoing forms two asymmetry channels at ANT-TX and two interchannels of ANT-RX like this, switching controls between two asymmetry channels is realized by integrated silicon chip for driving, level connects the integrated LNA chip of GaAs behind the ANT-RX passage, constitutes receive path.
