RF Transceiver Modules are commonly used for various radio transmissions, in order to reduce the cost and complexity associated with constructing wireless networks. The WT32I-E-AI61C is one type of such module, designed for low power and low cost operation.

Features

• Frequency band: 2.4 GHz ISM band
• Modulation type: GFSK
• Receiver Sensitivity: -95dBm
• Transmit Power: +20dBm
• Interface: UART/SPI/I2C
• Package Type: 19pin QFN

Application Field

The WT32I-E-AI61C is mainly used in applications where the transmission range is short, such as Bluetooth wireless data transfer, home automation, and sensor networks. It is also suitable for voice transmission and local data exchange. With its low power feature and small package size, it is an excellent choice for low-cost and low-power embedded solutions.

Working Principle

The WT32I-E-AI61C consists of two sections - a transmitter and a receiver section. On the transmitter section, an RF signal is generated by a low voltage and low power PLL synthesizer from a modulation signal. On the receiver section, the signal is first down-converted to an Intermediate Frequency (IF) signal, then converted to a baseband signal and finally demodulated.The WT32I-E-AI61C has an integrated voltage regulator, which enables it to be used in situations where the associated circuit applications have different operating voltage domains. It also uses an integrated power amplifier and antenna switch module, which provides for optimized power transmission while reducing the overall external component cost.

Conclusion

The WT32I-E-AI61C is a valuable RF transceiver module providing a reliable and cost effective solution for short range wireless applications. Its features include a low power PLL synthesizer, integrated voltage regulator, and an integrated power amplifier and antenna switch module. Its application field includes Bluetooth wireless data transfer, home automation, and sensor networks.
