  1. RF4CE - The Wireless Remote Control That Keeps Coming Back
    9/28/2010
    The consumer electronics industry has always had something of a love-hate relationship with remote controls. It’s painful to design and ship a new remote control with every product, but attempts to come up with an interoperable standard have been plagued with problems.
  2. Designing Ultra Low Noise Amplifiers For Infrastructure Receiver Applications
    9/27/2010
    Amplifiers used in wireless infrastructure receiver applications have the key requirements of low noise, high linearity, and unconditional stability. In order to meet these needs, Skyworks has developed a new family of low noise amplifiers (LNAs) implemented in 0.5 µm enhancement mode (E-Mode) pHEMT. The SKY67101-396LF, covering 0.7–1.0 GHz, and the SKY67100-396LF, covering 1.7–2.0 GHz, are appropriate for application in GSM, WCDMA, TDSCDMA, and LTE infrastructure receiver chains.

  4. The Most Common Power Meter Mistake
    9/21/2010
    At least 50% of all power meter users make this mistake. It has happened to you. You measured an RF power level and later someone said, "...but I measured the power and got a different number." Who was right? Measuring RF power appears easy. Modern wattmeters and power meters are simple to use, and can provide digital measurement data to several decimal places in dBm or watts. But if they are so accurate, why is it so difficult to make good measurements? If you are making the most common mistake, correcting for it will dramatically improve your measurement accuracy.

  6. White Paper: Configuring Software-Defined WLAN Test Systems
    9/16/2010
    By National Instruments Corporation Today, it's hard to picture life without wireless local area network (WLAN) devices. In fact, the use of WLAN or Wi-Fi extends to many products, such as access points, routers, and even cell phones. As the market for WLAN devices has grown, so has the number of engineers performing WLAN measurements. This white paper offers basic insights into WLAN test measurement options and an overview of the physical layer.

  10. White Paper: Migration From WiMAX Release 1 To WiMAX Release 2
    9/16/2010
    The WiMAX Forum is accelerating its development efforts to produce Release 2 equipment based on the upcoming IEEE Standard 802.16m. The new release will offer significant coverage and capacity improvements over WiMAX Release 1. The development timeline for Release 2 targets early engineering trials by mid-2011, with WiMAX Forum certification of equipment by the end of 2011, early commercial availability by mid-2012, and general commercial availability with rich terminal offerings in 2013. This article provides basic recommendations for migration from Release 1 to Release 2, assuming that the migration starts from specific typical WiMAX network deployment scenarios. By the WiMAX Forum
