It is Small size, high performance, integrated-circuit RF receiver offering 0.1-6000 MHz of operational range, low current consumption and high gain. This receiver consists of several stages, each designed to fulfill the basic functions of RF-reception and prepares the analog wireless signal for further processing.

Applications

The MAX1471ATJ/V+T RF receiver is offered in low power, packaged solutions and is suitable for a wide range of different applications. It is suitable for professional and amateur radio, military and government communications, and remote sensing applications. The integrated V+T converter provides enhanced performance bandwidth and improves system dynamic range. This device can also be used for various medical applications, such as remote measurement of vital signs in hospitals, medical monitoring, ambulatory care and diagnostic systems.

Working Principle

The MAX1471ATJ/V+T RF receiver consists of several stages, beginning with a low noise amplifier (LNA). This stage amplifies the incoming signal before further processing. Following this is a voltage controlled variable gain amplifier (VGA or VCA) that is used to adjust the signal to a predetermined level. The signal then passes through a limiter stage, this reduces the dynamic range of the signal and adjusts it to levels which can be handled by subsequent circuits. The receiver is then demodulated to extract the useful information. Finally, the V+T converter converts the analog signal into a digital form.

Conclusion

The MAX1471ATJ/V+T RF receiver provides a comprehensive solution for RF receiver applications. The combination of low noise, high gain and low power consumption makes it ideal for many different applications, ranging from professional radios to medical receivers. The integrated V+T converter further enhances the device performance and makes it one of the best RF receiver options available on the market.
