A multistandard, multiband SoC with integrated BT, FM, WLAN radios and integrated power amplifier

The growing occurrences of WLAN, BT, and FM on the same mobile device have created a demand for putting all three on the same die to save on die size, I/O count, BOM, and ultimately cost. Common blocks such as crystal oscillator, bandgap, and power management units can be easily shared. This paper presents a solution in which 802.11a/b/g WLAN, single-stream 11n (SSN) WLAN, BT, and FM subsystem and radio are integrated on a single die.

20.2 A 16TX/16RX 60GHz 802.11ad chipset with single coaxial interface and polarization diversity

The IEEE 802.11ad standard supports PHY rates up to 6.7 Gbps on four 2 GHz-wide channels from 57 to 64 GHz. A 60 GHz system offers higher throughput than existing 802.11ac solutions but has several challenges for high-volume production including: integration in the host platform, automated test, and high link loss due to blockage and polarization mismatch. This paper presents a 802.11ad radio chipset capable of SC and OFDM modulation using a 16TX-16RX beamforming RF front-end, complete with an antenna array that supports polarization diversity. To aid low-cost integration in PC platforms, a single coaxial cable interface is used between chips. The chipset is capable of maintaining a link of 4.6 Gbps (PHY rate) at 10 m.

A Single-Chip Bluetooth EDR Device in 0.13μm CMOS

A low-power single-chip Bluetooth EDR device is realized using a configurable transformer-based RF front-end, a low-IF receiver and direct-conversion transmitter architecture. It is implemented in a 0.13mum CMOS process and occupies 11.8mm2. Sensitivity for 1, 2 and 3Mb/s rates is -88, -90, and -84dBm and transmitter differential EVM is 5.5% rms.
