توضیحات
The RDA5815s is a fully integrated direct conversion RF front end for DVB-S,DVB-
S2&ABSS,MMDS digital satellite Reception standard CMOS process. The receiving frequency
range is from 250MHz to 2300MHz, and the baseband filter’s bandwidth can be selected from 4MHz to 40MHz with 1MHz step.
The rda5815s consists of a variable gain LNA, quadrature downconverter, variable IF gain amplifiers, variable low-pass filters, reference oscillator, VCOs, synthesizer and output baseband amplifier to drive external ADC.
Based on RDA’s some innovative technique, the rda5815s offers excellent phase noise and very low implementation loss, required for advanced modulation systems such as 8PSK and DVB-S2. This tuner RF IC does not require a balun and its fully integrated design saves valuable board space and simplifies RF layout.
