TRF7904RGPR Working Principle

The TRF7904RGPR receiver is RF optimized to enable high data rates and reliable communications. It is based on a 2.4v to 3.6v supply voltage and consumes limited power upon start-up, making it suitable for battery-powered applications. The receiver is equipped with programmable packet format, adjustable data rate, and automatic frequency correction.

The data rate is adjustable in multiples of the symbol rate adjustable up to 1000kb/s. The automatic frequency correction feature maintains a constant carrier frequency, despite changes in the environment or environmental variations. Adaptive bandwidth control further optimizes receiver performance and improves data throughput.

The intelligent antenna diversity feature is used to reduce multipath fading and interference, as well as to achieve better wireless communication link performance. It uses two non-isolated antennas to improve the system performance, further reducing packet errors and increasing the data rate. The receiver also includes a temperature sensor for monitoring system temperatures and detecting system overheating.

The TRF7904RGPR receiver is designed to provide reliable and efficient communication with ultra-compact, low-power devices. It offers programmable packet format, adjustable data rate, adaptive bandwidth control, intelligent antenna diversity, AES-128 encryption engine, as well as temperature sensor for monitoring system temperatures and detecting system overheating.
