The RDA5815 is a fully integrated direct conversion
RF front end for DVB-S,DVB-S2&ABS-S,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 rda5815 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 rda5815 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.

Direct AGC control
Through the AGC pin input, the receiver chain’s gain can be directly controlled by the baseband solutions. The
receiver gain changed inversely with the AGC control signal, this means that when AGC signal goes high, the
receiver gain will drop to relevant level and vice versa.
