An x86 standard operating system compliant System-on-Chip (SoC) with a dual core ATOM processor and a custom interconnect fabric to enable modular design is presented. The 32 nm SoC includes integrated PCI-e Gen 2, DDR3, legacy I/O, voltage regulators, clock generation, power management, memory controller and RF portion of a WiFi transceiver in a 32 nm high-k/metal-gate RF CMOS process with high resistivity substrate. The integrated RF transceiver for 2.4 GHz 802.11g operation achieves a receive sensitivity of -74 dBm, -8 dBm IIP3 and a transmit output power of 20.3 dBm (-25 dB EVM) at 14% TX RF efficiency.

A 2.4GHz WLAN transceiver is presented with a fully-integrated highly-linear 28.4dBm PA, 34dBm T/R switch, 240MS/s DAC and 320MS/s ADC (high OSR for relaxed filtering), DPLL and fractional LOG, in 32nm CMOS. For 802.11g 54Mbps, without linearization the TX delivers 19.8dBm at 12.5% efficiency (PA 21.6dBm/19.7% PAE) for -25dB EVM and mask-compliant 22.8dBm/18.5%, while the RX achieves 4.8dB NF, -69dBm sensitivity, and -8dBm IIP3.
