RF Transceiver ICs

JN5139/001-515 is a type of RF transceiver IC. It has wide application scope and working principle.JN5139/001-515 is a transceiver IC which integrates a RF transceiver,a MCU, a vairous digital peripherals and an application processor. It is suitable for low rate wireless applications, such as intelligent home appliances and home automation. It contains a lot of subprograms, such as 8051 based MCU and an application processor. The power from radio frequency frequency(RF) antenna will be converted into decode signals. After decoding, it will adapt the logic control to achieve signal processing. JN5139/001-515 is able to transfer radio frequency signals,including Zigbee, Proprietary protocol and so on,via a single chip solution.The working principle of this transceiver is simple. When transmitting, it firstly convert the digital data to be transmitted into an electrical signal through digital signal processing. And then it will modulate the signal by using frequency modulation, amplitude modulation, phase modulation and other modulation methods. After that,it will amplify the electric signal and transfer it to the frequency conversion device. Finally, the frequency conversion device convert the electric signal into a radio frequency signal with high power efficiency. After that, the signal will be naturally radiated by an antenna. For receiving, the radio frequency signal received by antenna will be firstly converted by the frequency conversion device back to the electric signal. And then, the electric signal will be demodulated by a demodulator circuit, then it will demultiplex the signal into digital signals and then converted back to the original digital data. The JN5139/001-515 transceiver chip has numerous applications, such as smart home systems, remote control equipment, home security and alarm systems, long-range wireless telemetry systems, asset tracking and wireless industrial process control. In a nutshell, the JN5139/001-515 transceiver IC is a powerful tool for transferring radio frequency signals in a wide range of applications, including Zigbee, Proprietary protocol and so on, thanks to its single chip solution. It works well with either transmitting or receiving digital signal by using frequency modulation, amplitude modulation,phase modulation and etc. Finally, it contains a lot of features to satisfy various demands in the communication field.
