General Description：

The RDA8206 RF transceiver is a fully integrated single-chip CMOS RF transceiver, fabricated in proven CMOS technology, for the Third Generation Partnership Project (3GPP) specification for the Universal Mobile Telecommunication System (UMTS) and GSM applications for 850MHz, 900MHz, 1800MHz and 1900MHz bands. The chip is specifically designed for UMTS Time Division Duplex (TDD) mode or TD-SCDMA standard that operates in the dual-band range of 1880 to 1920 MHz and 2010 to 2025 MHz (1.28 Mcps option) and for GSM mode that operates in the quad-band range of 850MHz, 900MHz, 1800MHz and 1900MHz.
