Embodiment Construction

[0014] Please refer to figure 1 As shown, the dual-mode wireless local area network module includes a radio frequency part and a base frequency part. The radio frequency part includes a pair of dual-frequency antennas 40, a radio frequency front-end circuit 30, and a radio frequency integrated circuit 20 (Radio Frequency Integrated Circuit, RFIC). The baseband part includes a baseband integrated circuit (Base-band Integrate Circuit, BBIC) 10 and an interface circuit (not labeled) electrically connected to the radio frequency integrated circuit 20, and a small peripheral component expansion interface (Mini-PCI, not labeled, set in On the laptop 600).

[0015] The electrical connection between the radio frequency integrated circuit 20 and the baseband integrated circuit 10 can be easily obtained by a dual-mode chip solution based on Synad. The electrical connection between the baseband integrated circuit 10 and the expansion interface of small peripheral components has been The pri...

Abstract

The present invention relates to a bimodule radio local area network module. The module can be assembled in the electronic equipment for making radio communication with other electronic equipment. The module includes small peripheral component extended interface unit, bimodule baseband unit electrically connected with said interface unit, bimodule radio-frequency unit electrically coupled with the described bimodule baseband unit, radio-frequency headend circuit electrically-coupled with the bimodule radio-frequency unit and a pair of double-frequency antenna electrically coupled with the radio-frequency headend circuit. The radio-frequency headend circuit has antenna diversity circuit used for selecting antenna and controlling make / break of receiving and transmitting path of radio-frequency headend circuit.

Description

【Technical Field】 [0001] The invention relates to a dual-mode wireless local area network module and its radio frequency front-end circuit. 【Background technique】 [0002] With the continuous development of Wireless Local Area Network (WLAN), its performance in the 2.4GHZ industrial, scientific and medical (Industrial, Scientific and Medical, ISM) frequency band has gradually approached ordinary wired Ethernet. (Ethernet). In the paper "Technology economics of standards based WLAN solutions and cost of ownership" by Juan Figueroa, Bill Garon, Bob Pearson and AL Pertrick of Intersil (from http: / / www.eetasia.com / Design corner: RF / Wireless Design / Technical Archiwes), analyzed the cost of the WLAN solution, and pointed out that the wireless technology and communication protocol recommended by the IEEE 802.11 working group are quite competitive with the mature Ethernet technology. The analysis of chip and packaging technology further shows the advent of the wireless LAN era. [0003]...
