集成电路芯片资料和参数

芯片型号:RDA5156

功能特点

The rda5156 is a fully integrated direct convertion RF front end supporting all worldwide terrestrial and cable TV standards.

The rda5156 extends the unmatched performance and design simplicity while further reducing footprint size.

No external LNAs, tracking filters, or SAW filters are used.

Based on RDA’s some innovative technique, the rda5156 offers excellent phase noise and very low implementation loss, required for advanced modulation systems such as QAM256, QAM64. This tuner RF IC require a balun and its fully integrated design saves valuable board space and simplifies RF layout.
