z Main Chipset Specification

MAC/Baseband Processor

The RT2880 SOC combines Ralink’s 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 perform ance,
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 “inte lligent”
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 802.11 n WLAN
performance without the need to upgrade to an expensive host SOC.

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 int egrated
channel-selection filters. The transmit chain includes integ rated
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 (10M Hz) and
wide- band (20MHz). Their bandwidth is calibrated by an inte rnal
autonomous calibration circuit. To help IQ mismatch calibrat ion, 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.
