The chip is specifically designed for UMTS Time 3/4 Low noise RF front-end Division Duplex (TDD) mode or TD-SCDMA standard 3/4 Image-reject down-converter that operates in the dual-band range of 1880 to 1920 3/4 High performance A/D converter MHz and 2010 to 2025 MHz (1.28 Mcps option). 3/4 On-chip DC offset cancellation The chipset consists of the RDA8207 transceiver and RDA8252 power amplifier for TD-SCDMA and RDA ES11 TX.RX switch. This RF chipset provides a complete solution connecting antenna to baseband for TD-SCDMA standard, eliminating the expensive IF SAW filter. All bulky components, such as RF VCO, loop filters, and tuning inductors, are completely integrated on chip. Direct up-conversion transmitter for TD-SCDMA 3/4 Highly linear I/Q modulator 3/4 RF VGA with over 80 dB APC control 3/4 Minimum Carrier Leakage 3/4 Integrate on-chip analog baseband function, support 10 ~ 12 bit parallel digital I/O data interface 3/4 - Fractional-N Frequency Synthesizer 3/4 Fully integrated on-chip VCO & loop filter 3/4 Low phase noise 3/4 Fast locking (<30s) Receive Path The receiver is a zero-IF architecture which includes an RF front-end (LNA, Mixer), an analog channel filter and a sigma-delta A/D converter which is followed by a digital signal processing unit (DSP) that performs digital filtering, digital PGA, and DC-offset cancellation. 3/4 Support 26MHz TC-VCXO or DCXO, Can output two (13MHz or 26MHz) system clocks to baseband externally 3/4 SPI 3-wire or 4-wire serial interface bus Transmit Path 3/4 Support both analog I/Q baseband data interface and digital I/Q baseband data interface 3/4 1.8V/2.8V interface voltage level option The transmitter is a direct up --- conversion architecture which includes a low-pass baseband filter, a highly linear I/Q modulator and a large dynamic range RF VGA and a driver for external power amplifier (PA). 3/4 Integrate on-chip LDO, support 3.3V ~ 4.2V external battery 3/4 40-PIN 6mm x 6mm QFN package RF Frequency Synthesizer 3/4 0.13m CMOS technology process The on-chip Local Oscillator (LO) is generated by dividing-by-2 the VCO output of a sigma-delta modulated Fractional-N PLL.
