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.

Interview: Element Six's Adrian Wilson
Adrian Wilson, Head of Element Six's Technologies Division, discusses the firm's GaN-on-diamond technology.
USB Coaxial Switches Aid Test And Measurement
In RF and microwave applications, USB coaxial switches offer various options for measuring multiple DUTs or performing multiple tasks with a single connection.
Get A Handle On Power Handling For SMD Components
This application note concisely presents recommendations for engineers designing a PCB for mounting SMD terminations, attenuators, and resistors.
Wireless Power To The People
While wireless power solutions have been evolving, solar charging solutions could eventually overtake them, given the convenience of not having to use charging pads and other accessories.
UWB RFID System Cuts Coupling By 20 dB
By applying ultra wideband (UWB) technology to RFID applications, it is possible to overcome some of the limitations of the current narrowband RFID technology.
New Modulation Technology Augments RF Spectrum
With the addition of the Transpositional Modulation (TM) format, it is estimated that data rates can be increased between 2 and 33 times over a given bandwidth—and that’s not including the benefits of new compressions.
Receiver Harvests 21-Hz Clock Signal From GSM Band
To conserve energy in wireless sensor networks, the wake-up receiver can harvest a digital clock signal from an existing wireless standard (i.e., a clock-harvesting receiver).
Mini Wireless Neural Sensor Consumes Just 10.5 μW
This wirelessly powered node is interrogated using a custom printed-circuit-board (PCB) antenna and COTS components in both a benchtop and in vivo setting.
Interview: Blake Peterson, Microwaves & RF “Living Legend”
Agilent Technologies' technical support pioneer looks back on his 45-year career.
Take A Model-Based Approach To Envelope Tracking
With envelope tracking providing a means to boost low efficiency in a power amplifier’s backoff region, it is useful to model the factors that may introduce distortion into a system.
Moving-Window FDTD Handles Propagation In Near-Real Time
The Moving Window Finite Difference Time Domain (MWFDTD) is well suited for porting to the GPU, as calculations can be made in parallel to completely utilize the GPU’s power.
Picking A Winner
The “Best of Microwaves” awards were conceived to recognize those companies that are reaching and serving engineers most effectively online—via technical resources like white papers, videos, blogs, and social media.
Intermodulated Regenerative Receivers Satisfy Terahertz-Imaging Needs
Thanks to their non-coherent nature and narrow bandwidth limit, super regenerative receivers (SRRs) are well suited for terahertz imaging applications using continuous-wave excitation.
10-Gb/s Linear Burst-Mode Receiver Reaches 85 dBΩ Gain
This linear burst mode receiver, which provides impressive linearity, sensitivity, dynamic range, and preamble length, was designed in 0.25 μm SiGe:C BiCMOS technology.
Divide-By-Three ILFDs Operate Beyond 280 GHz
Work on frequency dividers has led to G-band (140~220 GHz) and H-band (220~325 GHz) divide by 3 injection locked frequency dividers (ILFDs), which can be used in a millimeter wave PLL.
