The steep growth of digital-content consumption and increasing reliance on wireless networks has resulted in emerging standards such as IEEE 802.11ac. By employing spatial diversity, Multi-user MIMO and high-density modulation (up to 256-QAM), 802.11ac MIMO radios can provide significantly increased throughput, link robustness, and range while maintaining(More)
A front-end circuit of a System-on-a-Chip (SoC) containing an IEEE 802.11b/g/n wireless LAN (WLAN) and a Bluetooth transceiver is presented. This SoC integrates a WLAN power amplifier (PA), a transmit-receive switch (T/R switch), a process and temperature insensitive power detector, and a low-noise amplifier (LNA) that is shared between WLAN and Bluetooth.(More)
Markedly different levels of alkaline phosphatase production have been found in paired osteosarcoma cells and normal skin fibroblasts grown in tissue culture from 12 patients with osteosarcoma. In all cases, the osteosarcoma line contains significantly more alkaline phosphatase than does the paired normal line from that same patient. These criteria may be(More)
