Description
Technical field
The utility model relates to a kind of wireless communication apparatus, particularly relate to a kind of can compatible particular radio-frequency signal and the bimodulus communication chip of bluetooth signal.
Background technology
In the age of mobile communication prosperity today, it is main demand that transmission equipment day by day is inclined to wireless network.And the Radio Transmission Technology that is applied to QWERTY keyboard and mouse now is broadly divided into infrared and radio (infrared, IR) transmission and radio frequency (radio frequency, RF) wireless transmission.
The infrared and radio transmission has uses simple and advantage with low cost, but it also has the too weak and too strong shortcoming of directivity of communication distance ability too short, that penetrate physical obstacle.Because of the directivity of infrared and radio transmission is too strong, so when carrying out the transfer of data of computer and Wireless Keyboard or wireless mouse with infrared ray, the user must select its placement location very modestly, if choice of location is not good, then has the possibility of bust this.Compare, adopt the keyboard and the mouse of wireless radiofrequency transmission to have more advantage.
Adopt the keyboard of wireless radiofrequency transmission and mouse to remove to have and use simple and advantage with low cost, have also that communication distance ability far away, that penetrate physical obstacle is strong, the advantage of theaomni-directional transmission pattern.And because of wireless radiofrequency transmission tool theaomni-directional transmission pattern, so transmit when carrying out the transfer of data of personal computer and Wireless Keyboard or wireless mouse with wireless radiofrequency, the user can select at any angle that placement location transmits data.Usually the radio frequency band that is applied to Wireless Keyboard and wireless mouse is particular radio-frequency and bluetooth.Above-mentioned particular radio-frequency frequency range can be 27MHz, and the radio frequency band of bluetooth can be from 2400MHz to 2483.5MHz.
Use the keyboard or the mouse of 27MHz radio-frequency technique to have advantage low-cost and low consumpting power, but also have other radio frequencies supplier's keyboard or mouse is incompatible and the shortcoming of a kind of communication link mode of tool only.Use the keyboard or the mouse of Bluetooth technology, then to all different suppliers bluetooth keyboard or mouse tool compatibility, and in the micronet of a bluetooth, can comprise the bluetooth equipment of eight different keyboards or mouse simultaneously, one of them equipment is master unit, and all the other seven equipment are from the unit; Yet, use the keyboard of Bluetooth technology or mouse but to have the keyboard of high flow rate power and ratio use 27MHz radio-frequency technique or the shortcoming that mouse spends more cost.
Because of using the keyboard or the mouse of 27MHz radio-frequency technique and Bluetooth technology, have its pluses and minuses separately, so the user can select suitable keyboard or mouse because of its demand is different.But because of the communication module of accepting signal that uses 27MHz radio-frequency technique and Bluetooth technology manufacturing to form now, be installed on respectively in the different chips, can't produce in a chip can compatible 27MHz radio frequency and the receiver of two kinds of signals of bluetooth, causes user's inconvenience.
Figure 1A is the communication system of known particular radio-frequency technology.With reference to Figure 1A, the user is by using 27MHz radio frequency keyboard or mouse 111 Data transmission, this keyboard or mouse can be via 27MHz radiofrequency launcher 113 emission signals, data are transmitted with the radio frequency form, after this, receive signals via 27MHz radio frequency receiver 115 again, and by USB (USB) interface with transfer of data to computer.
Figure 1B is the communication system of known Bluetooth technology.With reference to Figure 1B, the user is by using bluetooth keyboard or mouse 121 Data transmission, this keyboard or mouse can be via bluetooth transmitters 123 emission signals, data are transmitted with the bluetooth form, afterwards, receive signals via Bluetooth Receiver 125 again, and by USB interface with transfer of data to personal computer.
