Abstract :
An 802.11n-draft-compliant 2times2, 2-stream MIMO radio SoC, incorporating two dual-band RF transceivers, analog baseband filters, data converters, digital PHY and MAC, and a PCI Express interface, has been integrated in a standard 0.13- mum digital CMOS technology with a die area of 36 mm2. The receiver achieves noise figures of 4 dB and 6 dB, respectively, at 2.4 GHz and 5 GHz. The transmitter EVM for a 2-stream, 40-MHz-bandwidth 64-QAM OFDM signal is - 31 dBc at 2.4 GHz and -8 dBm output power and -31.5 dBc at 5 GHz and - 4 dBm output power.
