Pushing Software Radio Closer To The Antenna
New technologies offer engineers of SDR (software-defined radio) systems diverse opportunities to perform digital-signal processing much closer to the antenna than ever before. Strategies for doing so include the latest wideband data converters, monolithic receiver chips, compact RF tuners, and remote receiver modules using gigabit serial interfaces. Each approach presents benefits and tradeoffs that must be considered in choosing the optimal solution for a given application.
Properties, Test Methods, And Mounting Of Dielectric Resonators
The most important material properties for a Dielectric Resonator (DR) are its dielectric constant (εr), Unloaded Quality Factor (Qu), and temperature coefficient of the resonant frequency (τf).
EM Simulation: Evolution Within Circuit Design
Electromagnetic (EM) simulation has become commonplace for RF and microwave circuit designers. This viewpoint article examines current trends with regard to how designers use EM tools inside of circuit simulators. Dr. John M. Dunn, AWR
True Differential Measurements- Characterization of Balanced Devices
Differential devices offer advantages like noise immunity, low crosstalk, high integration density, and reduced power consumption. However, they also require special measurement capabilities. There are essentially two different measurement methods available: virtual measurements, and true differential measurements.
Enhanced Interconnect Medium Simplifies Test & Verification
In high performance embedded systems test application, the requirement for accurate measurement of AC and DC parameter is often critical. During development phase, IC devices are not permanently attached to the target board. Instead IC devices are connected via interconnect medium to the target board.
