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.

Multilayer Organic Capacitors Exhibit Exceptionally Low Dielectric Absorption
Low k dielectrics with low dielectric absorption (DA), such as multilayer organic capacitors, can benefit sample and hold circuits, where DA can cause voltage error at the output due to charge recovery.
288-GHz CMOS Source Radiates -4.1 dBm
This all CMOS submillimeter wave imaging chipset comprises two magnetically coupled, balanced triple-push oscillator cores with an on-chip antenna.
DAC-Based Multimode Transmitter Offers Signal Bandwidth To 2.2 GHz
At the heart of this multimode transmitter is a high-speed DAC, which achieves high sampling frequency, high in-band linearity, and low spurious levels to serve as a potential solution for narrowband or wideband applications.
Chip-To-Chip Electrical Interconnect Transmits 1.8-ps Pulses From 50 To 300 GHz
The observed pulses of this electrical interconnect prototype can support a 100-Gb/s digital link using an air-spaced, two-wire transmission line, paving the way to connect short pulses in high-speed electronic circuits.
Interview: Bob Giometti, SkyCross

Interview: Martin Nuss, Vitesse Semiconductor
MWRF talks HetNets with Martin Nuss, Chief Technology Officer at Vitesse Semiconductor.
UHF-Band Folded Antenna Is Suitable For In-Body Wireless Communications
With the implementation of a folded antenna designed to operate in the ultra-high frequency (UHF) band, in-body technology advancements are made possible.
Radar Detects Disaster Victims’ Heartbeats
NASA and the US Department of Homeland Security have partnered on the development of a portable radar device that detects the heartbeats and breathing patterns of disaster victims trapped in large piles of rubble.
The Do’s And Don’ts Of LTCC
By keeping in mind LTCC’s limitations as well as applicable design rules, engineers can benefit from its use—particularly in compact RF and microwave components.
Interview: SenarioTek Co-Founders Simi Ghiasvand And Bob Alman
Microwaves & RF sits down with SenarioTek's Simi Ghiasvand,CEO & President, and Bob Alman, CTO.
The Case Is Made For WiFi In Hospitals
As long as quality of experience (QoE) levels are maintained, connecting medical devices to a hospital WiFi network can improve clinical workflows by providing wireless access to real-time patient data.
Imagine Yourself As A Network
While full communications technologies are not yet able to be embedded inside individuals, humanity’s large adoption of technology and desire to always be connected does make that future seem inevitable.
Broadband Radio’s LNA Shoulders Harmonic Rejection To 20 dB
This 100-MHz-to-10-GHz harmonic-rejecting LNA introduces harmonic rejection in the front-end LNA to relax the stringent matching required for harmonic-reject mixers.
SiGe BiCMOS Pulsed Radar Opens Door To Imaging And Gesture Recognition
While eliminating any RF or IF phase shifting or combining, this array architecture simplifies scaling to a larger number of nodes.
Space Mapping Outpaces EM Optimization In Handset-Antenna Design
By using a space mapping based modeling and design technique for handset antennas, it is possible to achieve significant time savings over direct EM based optimization.
