The RDA3308 is a single-chip dual-band RF front end for SCDMA and MC-SCDMA wireless communication, supporting 400/1800MHz dual-band applications.Comparing to   the previous RDA3300/01 chipset, RDA3308 integrates RF radio with baseband interface as well. RDA3308, RDA3314(400MHz PAM),RDA3319(1800MHz PAM) and RDAES01(SP2TSwitch) builds up a complete RF radio solution,which directly interface with antenna and baseband processor. All sensitive components,such as RF VCO,loop filters, and tuning inductors and varactors, are completely integrated into RDA3308.
