Main Chipset Specification MAC/Baseband Processor The RT2880 SOC combines Ralinks 802.11n draft compliant 2T3R MAC/BBP, a high performance 266-MHz MIPS4KEc CPU core, a Gigabit Ethernet MAC and a PCI host/device, to enable a multitude of high performance, cost-effective 802.11n applications. The RT2880 has two RF companion chips, the RT2820 for 2.4G-band operation and the RT2850 for dual band 2.4G or 5G operation. In addition to the traditional AP/router application, the chipset can be implemented as an WLAN intelligent NIC, drastically reducing the load on the host SOC, such as DSL/Cable or Multimedia Applications processors. Users can treat the WLAN iNIC as a simple Ethernet device for easy porting and guaranteed 802.11n WLAN performance without the need to upgrade to an expensive host SOC.

17mm x 17mm BGA-292 Package I/O : 3.3V/2.5V(RGMII), 3.3/5V PCI I/O 11b/g/n Transceiver RT2820 is a monolithic SiGe RF IC that integrates multiple half-duplex direct-conversion radio transceivers designed for IEEE802.11b/g/n WLAN systems or other wireless LAN applications operating in 2.4GHz ISM bands. The IC has two concurrent transmit channels and three concurrent receive channels. The multiple channels are designed to improve robustness and throughput during wireless operation. Each receive channel achieves low noise figure, high input sensitivity, high linearity, and high output power while consuming low DC power. Each receive path features a gain selectable, low-noise amplifiers (LNA), followed by RF-to-baseband I/Q demodulators, discrete-step variable-gain amplifiers and integrated channel-selection filters. The transmit chain includes integrated reconstruction filters, a baseband-to-RF I/Q modulator, discrete-step variable-gain amplifiers for power-level control, and pre-drivers for external power amplifiers. The modulator and demodulator are driven by internal VCO. The VCO is phase-locked by an internal 3-wire-interface PLL. The bandwidth of the integrated channel-selection filters and the reconstruction filters can be programmed to narrow-band (10MHz) and wide- band (20MHz). Their bandwidth is calibrated by an internal autonomous calibration circuit. To help IQ mismatch calibration, a baseband transmit-to-receive loopback feature is provided. A crystal oscillator using external crystal and three low dropout regulators (LDO) are also integrated. The RT2820 is housed in a 76-pin 9x9mm2 leadless QFN package and is well suited for PCMCIA, MiniPCI, PCI, USB boards or embedded applications. It is designed to work seamlessly with RT2860B and RT2880 baseband/Mac IC.
