Description
Technical field
The present invention refers to a kind of apparatus for receiving and transmitting radio signal that strengthens the signal transmitting and receiving function of a mobile communications device, especially refer to a kind of operation by the conversion diverter switch, make a processing of the nonpassage of signal wave filter that receives and transmit, increasing the intensity of signal, signal under the emergency receives and the apparatus for receiving and transmitting radio signal of transmittability thereby increase.
Background technology
Quick and the development highly along with wireless communication technology, light and handy mobile phone easily changes person to person's communication way greatly.By mobile phone, people can carry out information exchange whenever and wherever possible, and especially when emergency took place, the user can get in touch with the external world by mobile phone in good time, reach and rescue the purpose that the people saves somebody's life.Yet the transmission of known mobile phone, received signal situation are subject to the distance with nearest base station, and are subject to influences such as landform, atural object.Therefore, if the user is in mountain area or more remote place, the signal of base station is fainter, even can't be connected with mobile phone, make the user can't be successfully and the external world get in touch, this moment, therefore people's first chance was rescued in forfeiture if meet with emergency (as the mountain difficulty taking place, running into situation such as rifle).
Address the above problem, can increase the quantity of base station or improve transmission, the receiving ability of mobile phone.The former can increase the dealer's of system burden, and the latter may make mobile phone or to disturb other electronic installation by authentication.For instance, please refer to Fig. 1, Fig. 1 is the schematic diagram of a known R-T unit 10.R-T unit 10 can be used for a mobile communications device, as electronic installations such as mobile phone, personal digital assistants, it includes an antenna 100, an emission receiving key 102, a surface acoustic wave filter 104, a low noise amplifier 106, a frequency reducing module 108, a power amplifier 110, a raising frequency module 112 and a signal processing module 114.Emission receiving key 102 switches switch 115 by one and 116,118 in filter is formed, when connecing received signal, diverter switch 115 can be electrically connected to filter 116 with antenna 100 switchings according to a control signal Vc, then the signal that received of antenna 100 can be by filter 116 and surface acoustic wave filter 104 to remove most interference, through low noise amplifier 106 signal is amplified again, by frequency reducing module 108 signal is reduced to fundamental frequency at last and be sent to signal processing module 114 with output correlation signal (as voice, letter letter, image etc.).On the contrary, when transmission signals, antenna 100 is switched and is electrically connected to filter 118, the fundamental frequency signal of signal processing module 114 output rises to radio frequency by raising frequency module 112 with frequency, and via power amplifier 110 amplifying signal energy, remove unnecessary interference signal by filter 118 again,, transmit in the air by antenna at last to avoid interference other electrical appliance.
Therefore, if will strengthen the transmission-receiving function of R-T unit 10, can be by increasing the gain of low noise amplifier 106 and power amplifier 110.Yet the gain that increases low noise amplifier 106 can make the noise section of the signal that received be exaggerated, and therefore can reduce the quality of signal, and the gain that increases power amplifier 110 not only can influence other electrical appliance, also possibly can't pass through legal norm.
