LE79252BTC

LE79252BTC application field and working principle

The LE79252BTC is a low power, low voltage supply and highly integrated Quad-Band RF transceiver module designed by LEAPERTEK Semiconductor. It is ideal for applications such as GSM/GPRS, EDGE, and WCDMA/HSDPA systems. The LE79252BTC operates in wireless communication bands such as 850/900/1800/1900MHz. This RF transceiver module integrates a transceiver, IF, synthesizer, power amplifier, low noise amplifiers(LNAs), synthesizer, voltage regulator, and digital to analog converter on a single chip in an SMT package.

The LE79252BTC has an impressive range of features like low power dissipation, high attenuation accuracy, high linearity, low current consumption, and high output power. It also supports the Automatic Transmitting Power Control (ATPC), which allows the system to dynamically adjust the transmitted power to maintain the high quality of service. These features enable the LE79252BTC to offer a significantly improved performance over other RF transceiver modules.

In terms of working principle, the LE79252BTC operates in two separate stages - a receive stage and an transmit stage. It first receives the RF signal from the antenna and converts it into an analog signal. This signal is then passed through an intermediate frequency (IF) amplifier. Once it passes through the amplifier, it is then converted into a digital signal to be processed by the DSP. The DSP processes the digital signal and outputs a digital signal for transmission. The digital signal is then converted back into an analog signal and passed through the PA in order to amplify the signal and transmit it over the air. Finally, the signal is received by the target device, which processes it and then sends back a response.

The LE79252BTC can be used in several types of applications such as radio base stations, radios, handsets, and telecommunication systems. It is ideal for applications that require low power dissipation, low current consumption, and high output power. Additionally, it is also suitable for applications that require robust performance and reliability. The LE79252BTC is a perfect choice for wireless communication applications that require low power consumption.
