	White Paper: Configuring Phase-Coherent RF Measurement Systems: From MIMO to Beamforming Today, many wireless communications systems incorporate multiple input, multiple output (MIMO) antenna schemes to take advantage of the multipath signal propagation. In addition, many of today’s modern RADAR systems use electromagnetic beam steering as replacement for the traditionally mechanically steered transmit signal. Read this white paper to learn more about how these applications and others are some of the primary drivers behind the demand for multichannel phase-coherent RF measurement systems. Download now.

	Impact of Ultralow Phase Noise Oscillators To an electrical engineer, in an ideal world there would be no noise. But what is noise? What is electrical noise? Or more to the point: What is phase noise? As engineers, we know intuitively that low noise in a system is better than high noise. However, we must quantify this noise in commonly accepted units. We must also examine the difference in phase noise performance of commodity vs. low-cost, high-performance crystal oscillators. Understanding the cost performance trade-offs between oscillators is crucial to a system design. Download Now.
	Read Application Note: Scalar Network Analysis using USB Power Sensors A scalar network analyzer (like the Agilent 8757D) is the most popular instrument used for scalar stimulus-response measurements due to its moderate price, high freq coverage, and fast measurement speed. However, the USB sensor based scalar network analyzer provides advantages in terms of flexible setup, portable, multi-function, and cost. It can be a low cost, alternative replacement for the highly popular but discontinued 8757D. Get the SNA application note and free software tool to easily make scalar measurements on your PC.

	Read Application Note: Discover the cause of signal problems in 3 steps with vector signal analysis (VSA) software When measuring or troubleshooting digitally modulated systems, it is tempting to go directly to the digital demodulation tools. Making a random sequence of measurements on a system and watching for signs that something is wrong or questionable can produce useful results, but important things can be missed and a great deal of time wasted on unproductive or inefficient measurement approaches. A planned measurement sequence, the most reliable way to find the cause of signal problems, reduces the time it takes to isolate the root cause of a problem and mitigates the chances that other errors will be missed. This application note presents a planned measurement and troubleshooting sequence. From Agilent Technologies. Learn more.

	White Paper: Designing Ultra Low Noise Amplifiers for Infrastructure Receiver Applications 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.

	White Paper: Shielding RF Components at the Package Level Because OEMs want to introduce products into the market quickly, common platforms are used to reduce development time; but predicting interference between different designs is difficult. Electromagnetic shielding is necessary in RF/mW applications, but a retrofitted customer-level shield is costly. If the shield is integral to the design, however, the product is more efficient, cheaper, and faster to produce. This paper surveys shielding techniques, contrasting their performance and manufacturing efficiency. Download now.
