RF Transceiver ICs

The JN5142N/001-518 is a high-performance low power UHF transceiver integrated circuit (RFIC) from NXP Semiconductors, ideal for wireless data communication application.. This transceiver IC features built-in RF signal amplifier, crystal oscillator and frequency synthesizer.

Application Field

The JN5142N/001-518 is designed for low power wireless applications such as Zigbee, Remote Keyless Entry (RKE), remote control systems and active RFID tags. The RF transceiver features full integration of RF, PA and LNA elements, low power consumption, high-level sensitivity and a high-power output, making it suitable for various wireless data communication standards like Zigbee, 6LoWPAN, 802.15.4, Wi-Fi and Bluetooth.

Principle of Operation

JN5142N/001-518 uses a simple architecture to carry out the multistage data transmission process. The radio-frequency (RF) subsysytem consists of a RF signal amplifier, crystal oscillator and frequency synthesizer. The signal amplifier amplifies the RF signal from the antenna and sends it to the receive circuit. The crystal oscillator generates a reference signal, while the frequency synthesizer mixes the reference signal and the signal from the antenna, resulting in an intermediate signal with a frequency that can be manipulated. The intermediate signal is then sent to the transmitter, where it is converted into a form suitable for transmission.

The outgoing signal is then sent to an antenna. At the same time, the antenna also receives the incoming signal. This signal is then sent to the RF signal amplifier. The combined signals from the antenna and the amplifier are then sent to the receive circuitry, which filters and demodulates the signal. The resulting signal is then sent to the modulation and coding circuit, which further processes it and sends it to the baseband processor. The baseband processor then converts the signal into a digital format which can be used by the wireless station or any other device as required.

JN5142N/001-518 can be used to implement a wide range of wireless communications techniques, such as digital modulation and coding, frequency-hopping spread-spectrum, cyclic redundancy checks and error correction. The integrated technology of this device allows easy integration into embedded systems, as it does not require varying components or recalibrations over time. All-in-all, this device is a cost effective, reliable and advanced communication solution.
