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.

LNA Modules Promise Noise Down To 1.8 dB
Bridging applications ranging from broadband test equipment to aerospace and defense systems, a line of lownoise- amplifier (LNA) modules covers up to 18 GHz in bands. The NEL- 0618T620-5MH broadband LNA, for example, covers 6 to 18 GHz. It delivers at ...
HTS Filters Undergo Mechanical Tuning
HTS filters are known for their low insertion loss and high out-of-band rejection. Yet the performance of these filters may be negatively impacted by the thickness of the HTS film, dielectric-constant variations, and more. Tuning work is therefore ...
Combine Resources To Increase Reach
My prediction is that American Technical Ceramics cannot help but be slightly changed by this acquisition.
Negative-Resistance Cell Benefits Millimeter-Wave CMOS VCO
Many advanced communication and sensor systems include millimeter-wave voltage-controlled oscillators (VCOs) as key components. Recently, such devices have been realized in CMOS technology. Compared to III-V compound devices or ...
RF Synthesizer Integrates VCOs For Operation To 5 GHz
Equipment manufactures have been increasingly demanding space and cost-efficient solutions for radio applications with frequencies in the microwave range. A single-chip RF synthesizer with integrated voltagecontrolled oscillators (VCOs) is planning to ...
Demodulator Flaunts PGA With 24 dB Of Gain Range
Compared tosuperheterodyne architectures, a monolithic, high-linearity quadrature demodulator is vowing to reduce the component count of the receive signal chain in third-generation (3G) base stations by at least 75 percent. The TRF3710 demodulator ...
Raise The Visibility Of Remote Microwave Sites
For network operators, support for analogmicrowave monitoring equipment is not always easy to attain. Yet many companies are still relying on microwave transport for their communications network sites. To help those operators improve site ...
DDS-Based Signal Sources Conquer Semiconductor Characterization
With so many modern products relying on semiconductors, it is essential that the behavior of these devices be accurately evaluated. By emulating the waveforms found in actual applications, signal sources promise to help engineers accurately ...
UWB-IR Transmitter Dissipates 29.7 mW At 2.2-V Supply Voltage
In wireless-sensor newtork systems, many wireless terminals collect information like temperature and humidity. ZigBee has been billed as the optimal solution for such networks. Yet Ultra Wideband Impulse Radio (UWB-IR) may prove to be an even ...
Configurable Test Platform Operates To 6 GHz
The PXI Studio measurement system encompasses the PXI 3000 Series hardware modules, PXI Studio software with measurement plug-ins, and a PXI instrument chassis. The PXI 3000 Series modules now include the following: the 3025C, a 1-MHz-to-6-GHz digital ...
Passive Components Squeeze Into Tighter Spaces
Forays into new materials and engineering techniques are enabling passive components to heighten integration and performance while downsizing to meet emerging design needs.
Calibrator Kit Pinpoints Cable Loss
Every cable has some signal loss. In precision wireless test setups, that loss must be measured and compensated for in order to obtain accurate results. Such is the goal of the True-Cable kit, which measures the loss of cables used in precision wireless ...
PCB Layout Enables Lowest Thermal Resistance
Printed-Circuit Board (PCB) layout is critical to both thermal and RF performance. It is therefore crucial that designers consider the heat source as well as how the heat will be removed before the electromechanical design is finished. Texas Instruments, ...
UHF Satcom Antenna Covers 240 To 270 MHz
Mobile and shipboard applications demand high-performance operation from the zenith down to the horizon. Typically, such coverage requires two separate antennas and a switch to select from the two. In contrast, the Model SC-303B provides full ...
Single Sideband Schottky-Diode IC Mixer Covers 180 To 196 GHz
Broadband Telecommunication services and wireless local-area networks (WLANs) increasingly depend on millimeter-wave operation. Millimeter-wave components based on galliumarsenide (GaAs) and indium-phosphide (InP) monolithic microwave integrated ...
