Newell Shenzhen Electronic Technology Co., Bluetooth wireless technology is an extension of the narrowband signal spectrum part of digital coding technology Bluetooth module coding operations increased by the number of bits sent Bluetooth module, expanding the bandwidth used. Bluetooth uses frequency hopping spread spectrum manner. Frequency hopping spread spectrum such that the power spectral density of the signal bandwidth is reduced, thus greatly improving the ability of the system against electromagnetic interference, anti-crosstalk, so that Bluetooth wireless data transmission more reliable. According to the actual naming component package, which package SOT-23Q Q added to distinguish between IC SOT-23 package, several other elements in order to invoke the FET not wrong with the device name as the package name half a via-hole production Hengshui City, Bluetooth module, wifi Bluetooth module, Newell record (certified merchants) by Newell Shenzhen Electronic Technology Limited.
