Abstract:
1. A wireless communication device capable of switching to an external antenna module or an internal antenna module, the wireless communication device comprising: a housing; an internal antenna module installed within the housing for transmitting wireless communication signals; a direct current (D/C) power source for providing power; a signal processing module installed within the housing for processing the wireless communication signals; a first low noise amplifier coupled to the internal antenna module for amplifying the wireless communication signal received by the internal antenna module, the first low noise amplifier comprising: a switch comprising: a first equivalent inductance coupled to the D/C power source and the second terminal for blocking wireless communication signals; a second equivalent inductance coupled to the power input end of the first low noise amplifier and the third terminal for blocking wireless communication signals; a first capacitance coupled to the signal output end of the first low noise amplifier and the third terminal for blocking direct current; and a second capacitance coupled to the signal processing module and the second terminal for blocking direct current.
