General Description

The rda5880pt is a fully integrated direct convertion RF front end supporting all worldwide terrestrial and cable TV standards.
The rda5880pt 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 rda5880pt offers excellent phase noise and very low implementation loss, required for advanced modulation systems such as QAM256, QAM64. This tuner RF IC does not require a balun and its fully integrated design saves valuable board space and simplifies RF layout.
