A 2.4GHz WLAN transceiver with fully-integrated highly-linear 1.8V 28.4dBm PA, 34dBm T/R switch, 240MS/s DAC, 320MS/s ADC, and DPLL in 32nm SoC CMOS
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.
