General Description


The RDA5816sd is a RF switches integrated two-channel fully integrated direct-conversion RF front end for DVB-S2 application.
There have two channels integrated in rda5816sw with each channel separately controlled through the I2C bus.
With the RF switches, the two RF input signals can be switched between each other after setting the different switching modes. The receiving frequency range is from 900MHz to 2200MHz, and the baseband filter bandwidth can be selected from 4MHz to 40MHz with 1MHz step.
