The rapid commercialization of the IEEE 802.11n WLAN standard has increased the demand for higher data-rate and longer-range fully integrated MIMO SoCs that are backward-compatible with legacy IEEE 802.11a/b/g networks. This paper introduces a 3-stream, 3x3 MIMO WLAN SoC that utilizes three antennas to improve throughput, range, and link robustness. This chip integrates three dual-band transceivers,...
An International Agency for Research on Cancer (IARC) working group reviewed hundreds of scientific articles, and then reached the conclusion that current evidence is sufficiently strong to support a classification of possibly carcinogenic to humans for radio-frequency electromagnetic fields including those employed by cellular mobile telephones. It is curious to note that just days before the working...
The European Space Agency (ESA) released a Call for Proposals for the next Earth Explorer Core Mission in March 2005, with the aim to select the 7th Earth Explorer (EE-7) mission for launch in the next decade. Twenty-four proposals were received and subject to scientific and technical assessment. Six candidate missions were selected and further investigated in the preliminary feasibility studies (Phase...

This paper presents a 60-GHz millimeter-wave RFIC-on-chip triangular monopole antenna fabricated with TSMC 0.18-mum CMOS process. A planar triangular-monopole structure fed by the CPW microstrip line is adopted to design the on-chip antenna. The measured VSWR is less than two from 50 to 65 GHz. The simulated H-plane radiation pattern is nearly omni-directional, and the simulated antenna efficiency...
RF-over-fiber technology for military antenna remoting is discussed including system level metrics and examples of deployed systems. The design of a compact RF spectrum analyzer based on optical domain RF channelization is introduced.
