DA14682-00F08A92 RF/IF and RFID

RF Transceiver ICs are integrated circuits which offer range of essential functions for communication systems. The DA14682-00F08A92 RF Transceiver ICs is a radio transceiver with a 2.4 GHz frequency band. It is a fully integrated solution, combining a low power transmitter, receiver, band-pass filter, and a PA in one chip.

Application Field

The DA14682-00F08A92 RF Transceiver ICs is designed for low power radio communication applications, such as wireless remote controls, short-range industrial radio data communication, beacons, or consumer products such as mice, keyboards, or game controllers. The DA14682-00F08A92 is especially suitable for applications that require long battery life, low latency, and reliability such as building automation, data and energy logging, or home security.

Working Principle

The DA14682-00F08A92 is a 2.4 GHz radio transceiver with a highly integrated design. The device consists of four major functional blocks: the low power transmitter, the receiver, the band-pass filter, and the power amplifier. It operates on a spread spectrum at 2.4 GHz and supports Bluetooth Low Energy (BLE) standard, which is a part of the Bluetooth 4.0 Specification.

The RF transceiver\'s low power transmitter is responsible for generating and transmitting radio signals. The transmitter operates at 212 mA peak and 167 mA average current consumption, with a range of up to 250 m. To ensure a reliable transmission, the transmitter has integrated error correction and includes a watchdog and a CRC generator.

The RF transceiver\'s receiver is responsible for receiving the radio signals and demodulating them into digital data. The receiver uses synchronous demodulation and performs error detection using checksum calculation and parity bit validation. It has a current consumption of 67 mA peak, 60 mA average and a range of up to 250 m.

The band-pass filter is responsible for filtering the RF signal and ensuring that the RF transceiver operates only at the desired frequency. The band-pass filter is a 6th order filter with an insertion loss of 0.2 dB at its center frequency.

The final component of the DA14682-00F08A92 is the power amplifier, which is responsible for amplifying the signal and transmitting it at greater distances. The power amplifier has a current consumption of 7.5 mA peak and 5.4 mA average. It provides a range of up to 250 m.

Conclusion

The DA14682-00F08A92 RF Transceiver ICs is a highly integrated solution for low power radio communication applications. It combines a low power transmitter, receiver, band-pass filter, and a PA in one chip, which enables long battery life, low latency, and reliable signal transmission. The device is suitable for applications such as wireless remote controls, short-range industrial radio data communication, beacons, mice, keyboards, home security and more.
