Passive microwave components, Part 1: isolators and circulators
Basic passive microwave components have a vital role in RF/microwave system design. Despite the apparent simplicity of their functions, their performance is based on electromagnetic theory and Maxwell’s equations for insight into their operating principles and performance. Design for the demands of microwave signals is a very different situation than working at lower frequencies. Although […]

A quasi-Wheatstone bridge linear output circuit with one op amp
by Crutschow, Electro-Tech-Online community member A Wheatstone bridge is sometimes used to convert a variable resistance, such as a thermistor or strain-gage, to a voltage with zero volts out at some particular resistance (such as at 0°C for the thermistor). A bridge circuit has the advantage of being able to generate a 0V null output […]

Isolated analog amps provide accurate current measurements
Silicon Labs has introduced a family of isolated analog amplifiers, voltage sensors and delta-sigma modulator (DSM) devices designed to provide accurate current and voltage measurement with very low drift across temperature. Based on Silicon Labs’ robust, third-generation isolation technology, the new Si89xx family provides flexible voltage, current, output and package options to help developers reduce BOM […]

Optical amplifiers, Part 2: Basic implementations
Part 1 of this FAQ began an overview into the arcane world of all-optical amplifiers including where and why they are needed. Part 2 will briefly describe the four types and identify the two most commonly used for optical-fiber link signal boosting. Q: How “accurate” will this presentation be? A: Frankly, it will have large-scale […]
