RDA5880 Fully Integrated, Direct Down-Conversion Receiver for DVB-T

Download: For Datasheet

The RDA5880 is a fully integrated direct convertion RF front end for digital TV standards (DVB-T, ATSC, and DMB-T/H). The receiving frequency range is from 50MHz to 870MHz.


The RDA880 consists of a variable gain LNA, quadrature downconverter, variable low-pass filters, reference oscillator, VCOs, synthesizer, high performance adc, dsp and upconverter.


Based on RDA’s some innovative technique, the rda5880 offers excellent phase noise and very low implementation loss, required for advancedmodulation systems such as QAM16, QAM64. This tuner RF IC does not require a balun and its fully integrated design saves valuable board space and simplifies RF layout.
