11.29.22 -- How To Best Measure Phase Noise

Optocouplers, with their ease of design, simplicity, and smaller size, are being used to replace pulse transformers, which are much more difficult to design with relative to optocouplers.

S-band radars are used to produce accurate and reliable detection and ranging under severe weather conditions but at the expense of large size antennas.

The need for resistors with both high-frequency and high-power handling capabilities is growing, yet designers are making compromises. Z Power resistors are a solution offering the best of both worlds.   

A coupled inductor has two or more windings on a common core. They are used in a variety of power conversion circuits such as flyback, SEPIC, Fly-Buck, Cuk, ZETA, and multi-phase topologies.

Organizations in need of RF/microwave components and microwave subsystems often have difficulty identifying standard catalog solutions that will perform optimally, or even fit adequately, within their systems.

The R&S LCX LCR meter is ideal for measuring frequency, signal level, and DC bias. The R&S^® LCX sweep tool is an application program for conveniently performing such sweeps and displaying the results on charts.

The 5.8 GHz band is preferred for short-range digital communication applications because of the number of channels and the bandwidth available. This design provides high gain, robust overpower monitoring, and protection, all in a small footprint.

Antenna tuners in smartphones must be able to withstand ESD at every stage from device manufacturing to consumer use. However, confusion exists about the level of ESD protection required at each stage.

Power dividers and couplers are straightforward passive components. To design a component with high performance, designers must give attention to design detail, design execution, and fabrication quality. This article discusses power dividers and couplers and defines related terminology.
