Embodiment
Refer to Fig. 1, preferred embodiment of the present invention provides a kind of radio communication device 100, and it can be the electronic equipment that mobile phone, personal digital assistant (PDA), panel computer etc. have WIFI communication function.
This radio communication device 100 comprises WIFI antenna 10, duplexer 20, power amplifier 30, WIFI transceiving chip 40 and central processing unit 50.
WIFI signal for receiving WIFI signal from wireless router or other similar devices, and is sent to wireless router or other similar devices by this WIFI antenna 10.
This duplexer 20 for by the signal transmission path of WIFI signal and Signal reception path isolated, it is electrically connected between WIFI antenna 10 and WIFI transceiving chip 30, and the WIFI signal for being received by WIFI antenna 10 is sent to WIFI transceiving chip 30.Meanwhile, this duplexer 20 is also electrically connected between WIFI antenna 10 and power amplifier 40, for the WIFI signal after being amplified by power amplifier 40 is sent to WIFI antenna 10.
This power amplifier 30 is electrically connected between duplexer 20 and WIFI transceiving chip 40, for amplifying the WIFI signal transmitted by WIFI transceiving chip 40.In the present embodiment, the gain of this power amplifier 30 is about 20dB.
This WIFI transceiving chip 40 is electrically connected with central processing unit 50, this WIFI transceiving chip 40 detects received signal strength (the Received Signal Strength Indication of current WIFI signal for the WIFI signal transmitted according to duplexer 20, and the received signal strength of this WIFI signal is sent to central processing unit 50 RSSI).
This WIFI transceiving chip 40 also for modulating/demodulating WIFI signal, i.e. the WIFI signal that transmitted by duplexer 20 of demodulation, and modulate WIFI signal to be sent to power amplifier 30.
The power output of the received signal strength control WIFI transceiving chip 40 of WIFI signal of this central processing unit 50 for transmitting according to WIFI transceiving chip 40, and the gain of power amplifier 30 is controlled further by WIFI transceiving chip 40.Concrete, a received signal strength reference interval preset by this central processing unit 50, the received signal strength of WIFI signal received when central processing unit 50 exceed this received signal strength reference interval upper in limited time, this central processing unit 50 exports the first control signal to WIFI transceiving chip 40; When the received signal strength of the WIFI signal of central processing unit 50 reception is positioned at this received signal strength reference interval or prescribes a time limit lower than the lower of this received signal strength reference interval, this central processing unit 50 exports the second control signal to WIFI transceiving chip 40.
In addition, this WIFI transceiving chip 40 is also for when receiving the first control signal that central processing unit 50 exports, export the first power output (as 0 dBm), and send gain not enable signal to power amplifier 30, close gain (namely now the gain of power amplifier 30 is 0 dB) to control power amplifier 30.This WIFI transceiving chip 40 is also for when receiving the second control signal that central processing unit 50 exports, export the second power output (as-2 dBm), and send gain enable signal to power amplifier 30, open gain (namely now the gain of power amplifier 30 is 20 dB) to control power amplifier 30.
The using method of this radio communication device 100 is described below in two kinds of situation.
The first, when radio communication device 100 is in high field environment, such as, this radio communication device 100 and wireless router near time, the received signal strength of its WIFI signal is higher (such as higher than the upper limit of received signal strength reference interval).Now, the received signal strength of the WIFI signal detected is sent to central processing unit 50 by WIFI transceiving chip 40.Central processing unit 50 exports the first control signal, thus control WIFI transceiving chip 40 exports the first power output (as 0 dBm), and send gain not enable signal by WIFI transceiving chip 40 to power amplifier 30, gain (such as, now the gain of power amplifier 30 is 0 dB) is closed to control power amplifier 30.Now, the WIFI signal of being modulated by WIFI transceiving chip 40 is sent by WIFI antenna 10 after power amplifier 30 and duplexer 20.So, in the present embodiment, total transmitting power of this WIFI antenna 10 is the gain sum of 0 dBm(first power output and power amplifier 30).
The first, when radio communication device 100 is in feeble field environment, such as, when this radio communication device 100 is distant with wireless router, the received signal strength of its WIFI signal is lower (being such as positioned at received signal strength reference interval).Now, the received signal strength of the WIFI signal detected is sent to central processing unit 50 by WIFI transceiving chip 40.Central processing unit 50 exports the second control signal, thus control WIFI transceiving chip 40 exports the second power output (as-2dBm), and send gain enable signal by WIFI transceiving chip 40 to power amplifier 30, gain (such as, now the gain of power amplifier 30 is 20 dB) is opened to control power amplifier 30.Now, the WIFI signal of being modulated by WIFI transceiving chip 40 is sent by WIFI antenna 10 after power amplifier 30 and duplexer 20.So, in the present embodiment, total transmitting power of this WIFI antenna 10 is the gain sum of 18 dBm(first power outputs and power amplifier 30).
From above-mentioned two situations, when the received signal strength of WIFI signal is higher, total transmitting power of WIFI antenna 10 is lower, to use lower total transmitting power in preferably signal transmitting and receiving environment; And when the received signal strength of WIFI signal is lower, total transmitting power of WIFI antenna 10 is higher, to use higher total transmitting power in poor signal transmitting and receiving environment.
The WIFI transceiving chip 40 of radio communication device 100 of the present invention detects current received signal strength, central processing unit 50 according to the power output of this received signal strength control WIFI transceiving chip 40, and controls the gain of power amplifier 30 further by WIFI transceiving chip 40.So, this radio communication device 100 can adjust total transmitting power in different signal transmitting and receiving environment, and radio communication device 100 can be avoided because of Long-Time Service to occur the phenomenon of generating heat, battery electric quantity sharply declines.
