R820T2 Product Details
The R820T2 is a versatile tuner integrated circuit designed for software-defined radio (SDR) applications. This IC is widely used in SDR devices to provide efficient tuning and reception capabilities across a broad frequency range.
The R820T2 is a highly integrated silicon tuner that builds in low noise amplifier (LNA), mixer, fractional PLL, VGA, voltage regulator and tracking filter, eliminating the need for external SAW filters, LNA, balun, and LDO. Thanks the LNA architecture, R820T offers the lowest cost and high performance solution for digital TV application. On-chip LDO, high performance LNA, and small package enable R820T the perfect solution for both cost and font factor sensitive applications.
The TV stick, chip is USB DVB-T & RTL-SDR Realtek RTL2832U & R820T, The R820T2 is the main tuner chip used in most RTL-SDR dongles. Several months ago Rafael Micro ceased regular production of their R820T2 chip, and the older R820T has also been discontinued for some time too.
