Description
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.

The loop lna is used to generate the loopout signal.An on chip variable gain LNA is used to provide wide tuner dynamic range. A direct conversion architecture is used to convert the RF signal to in-phase and quadrature baseband signals. The signals required for direct conversion are all generated within the chip by a fully integrated PLL and a quadrature LO generator.
