RDA16112
The RDA16112 is a fully integrated direct conversion RF front end for DVB-S, DVB-S2, MMDS & ABSS digital satellite reception standard CMOS process. The receiving frequency range is from 900MHz to 2200MHz, and the baseband filter’s bandwidth can be selected from 4MHz to 40MHz with 1MHz step.
The RDA16112 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 innovative technique, the RDA16112 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.
RDA16112 has been in the reference design of most chip sets like Mstar, Sunplus, Novatek, ALI.
