Bluetooth Modular gold or silver handle _ Newell record (certified) _ Anhui Bluetooth module

Shenzhen Electronic Technology Co., Ltd. Newell Bluetooth wireless device for serial communication is handled through Bluetooth wireless RF links modular gold or silver, and utilize the Bluetooth module. Bluetooth module consists of a wireless transceiver unit, a link control unit and link management and host I / O units these three. On Bluetooth radio module, in order to improve the receiving performance while reducing the size and cost of the device, the companies have adopted some of their own unique technology, so that the structure of the Bluetooth radio modules are different. But the basic principle is what Bluetooth module, Bluetooth radio module generally consists of receiver module, transmit modules and synthesizers three modules. Newell Shenzhen Electronic Technology Co., Ltd. when the RF module is in the receive mode, the signal received by the antenna Bluetooth module surface treatment, through the filter and into the receiver module receiving the control switch. First, the control module receives from the transceiver module through a balun coming unbalanced signals into balanced signals (so you can get a high common mode rejection ratio); a weak signal is then received by a low-noise amplifier amplification, and finally the solution tune the circuit and the local oscillator signal from synthesizer effect provided by the carrier signal demodulated output.
