Microwaves & RF

Nancy Friedrich began her career in technical publishing in 1998. After a stint with sister publication Electronic Design as Chief Copy Editor, Nancy worked as Managing Editor of Embedded Systems Development. She then became a Technology Editor at Wireless Systems Design, an offshoot of Microwaves & RF. Nancy has called the microwave space “home” since 2005.

Hinode Satellite Captures Eclipse Image

Thanks to image sensors, the Hinode satellite was able to capture this image of a solar eclipse.

GPS III Program Achieves Power Milestone

With the powering on of the first satellite, the GPS III program is on track for scheduled launch availability.

Human Body Serves As Secure Communications Channel 1

Driving the evolution of the body-area network (BAN), this technology promises to provide a secure, low-cost method for implementing short-range, low-data-rate wireless communication with low power consumption.

Accurately Model UWB Antenna Pulses

With this modeling method, designers can analytically estimate the antenna effect on a transmitted pulse to include antenna pulse distortion into their ultrawideband (UWB) transceiver design.

UHF/UWB Antenna Supports Indoor Tracking

Using passive technology, a hybrid UHF/UWB antenna targets systems that merge identification and centimeter-class indoor localization.

4-x-LO-Based VCO Shrinks Bluetooth Transceiver

In a 5 x 5 mm, 40-pin QFN package, this Bluetooth v3.0+EDR compliant SoC minimizes LO pulling and reduces spurious emissions.

Ensure Success In SAW-Filter Choices

As long as they are correctly specified, surface acoustic wave (SAW) filters can simplify RF system design.

3D Beamforming Bolsters Small Cells

NEC and Ubidyne have joined forces to investigate the benefits of 3D beamforming small cells with the use of the latest active antenna technology. This approach can lower the cost of site acquisition and network-wide power consumption while improving network optimization.

GaN, Death, And Distrust 4

After working abroad on GaN developments, a 31-year-old engineer began to worry that his work could compromise US national security. He was later found dead, having supposedly committed suicide.

MEMS-Based Project Takes Flight

To track birds, a MEMS-based system houses a solar-powered GPS tag with rechargeable batteries, a tri-axial accelerometer, two-way data communication to a ground-station network, and automated data processing and visualization.

Device Diversity Drives Industry Forward

Rather than find a single semiconductor technology that is ideal for all applications, the RF/microwave industry relies on numerous device processes, each with its own set of strengths and weaknesses.

Reference Design Features IEEE 802.11ac and 802.11ad

By combining both IEEE 802.11ac and 802.11ad technologies, this reference board will allow users to more easily achieve increased speed, reliability, and range.

White Space Technology Makes Strides

Standards are advancing in the TV white spaces segment, leading to the first prototypes for IEEE 802.22 and an award for the M2M Weightless standard.

Aerial Platform Buoys UAV Sensor Development

With the hope of allowing any sensor/communication package to be mounted for testing, an aerial test bed has been created by modifying a Griffon Aerospace UAV.

Submarine-Cable Capacity Has Potential To Double

To lengthen the commercial life of cable in the face of aggressive increases in Internet demand, Soft Decision Forward Error Correction (SD-FEC) has been trialed in concert with a proprietary super channel technology.
