1General Description

BL-8188-EU1 product Accord with FCC CE and is 150 wireless USB adapter which has lower power consumption, high linearity output power, accords with IEEE802.11B/G/N, and supports IEEE802.11i safety protocol, along with IEEE 802.11e standard service quality. It connects with other wireless device which accorded with these standards together, supports the new data encryption on 64/128 bit WEP and safety mechanism on WPA-PSK/WPA2-PSK, WPA/WPA2.Its wireless transmitting rate rises 150M, equivalent to 10 times of common 11b product. The inner AI high gain ceramics antenna adapts different kinds of work environment. It’s easy and convenient to link to wireless network for the users using desktop, laptop and other device that needs connect to wireless network.

2The range of applying

MID, networking camera, STB GPS, E-book, Hard disk player, Network Radios, PSP, etc, the device which need be supported by wireless networking.

11The 6th Pin connect to antenna, please refer to design demand Connect to the 6th pin of Module

Connect to the 5th pin of Module

a)The current of 3.3V power supply must be >300mA, its ripple wave must be <30mV. The GND

pins of module and external antenna need to be an incorporated part. The ground plane should be larger, module and antenna should keep far away from interference source.

b)The sixth pin is 2.4G high frequency output, coplanar impedance of layout line between this pin

to antenna interfa ce should be 50Ω, we suggest use arc line or straight line, and beside the line there will be ground plane that its length as shout as possible, the longest length is no more than 50mm.

c)L1, C1, C2 constitute a π-type network that we preset, please make it close to antenna interface,

this π-type network is used to match the antenna parameters and control the radiation. It should be adjusted according to the real condition when being used.Normally you can only mount L1 that its parameters are: 10pF, NP0 material. No need C1 and C2
