Problems solved by technology
However, in order to realize the function of these wireless communication devices to receive TV signals, it is necessary to add a receiving antenna and a corresponding processing circuit to the wireless communication device. Adding an antenna will not only increase the size of the wireless communication device, which is not convenient for users to carry, but also increases the number of wireless communication devices. Assembly cost of the device

Embodiment Construction
[0011] figure 1 Shown is a wireless communication device 100 disclosed in an embodiment of the present invention, and the wireless communication device 100 may be a mobile phone, a personal digital assistant, or the like.
[0012] The wireless communication device 100 includes an antenna 10 , a matching circuit 20 , a switch 30 , a first chip 40 , a second chip 50 and a main chip 60 .
[0013] The antenna 10 is a multi-frequency antenna. By adjusting the physical structure of the antenna 10, it can transmit and receive the first wireless signal (television, TV) with a bandwidth of 470MHZ-806MHZ and the first wireless signal with a bandwidth of 88MHZ-108MHZ. Two wireless signals (Frequency Modulation (FM)) have a better effect. The antenna 10 sequentially transmits the received first wireless signal and the second wireless signal to the first chip 40 and the second chip 50 through the matching circuit 20 and the switch 30 respectively.
[0014] The matching circuit 20 is elec...

A wireless communication device comprises an antenna, a match circuit, a diverter switch, a first chip, a second chip and a master chip. The antenna is sequentially and electrically connected with the match circuit, the diverter switch, the first chip and the second chip. The match circuit, the first chip and the second chip are electrically connected with the master chip. The wireless communication device receives first wireless signals and second wireless signals through the antenna, wherein the first wireless signals and the second wireless signals have different frequency bands. The master chip is used for adjusting the matching parameter of the match circuit. The first chip and the second chip are used for receiving the first wireless signals and the second wireless signals respectively. According to the wireless communication device, one antenna is used for receiving the first wireless signals and the second wireless signals at the same time, so that the size of the wireless communication device is reduced, and the assembly cost of the wireless communication device is lowered.
Description
