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 […]
What are MEMS microphone arrays?
Beamforming arrays let designers create directional microphones using MEMS devices. With the right signal processing algorithms, these can enhance the user experience delivered by many types of audio equipment. An array can be simple, comprising as few as two microphones, and can be arranged in various configurations depending on the expected location of the preferred […]

RF Switches, Part 2: Analog and MEMS switches
Part 1 of this FAQ looked at the venerable electromechanical RF switch – still widely used in some applications, where it is the only viable option – and use of PIN diodes as RF switches. This part looks at analog and MEMS-based switches. Q: What is an analog switch? A: It’s conceptually straightforward: in basic […]
RF switches, Part 1: Mechanical and PIN-diode switches
There’s a ubiquitous and increasing need to switch RF signals ranging into the tens of GHz; four basic switch technologies – electromechanical, PIN diode, analog, and MEMS – are available, each with different features and capabilities. The need to switch RF signals has been a necessary design function since the earliest days of “wireless.” This […]

Understanding the difference between an incremental encoder’s PPR, CPR, and LPR
by Jason Kelly, CUI Incremental rotary encoders produce two square wave outputs as they rotate, from which the angular displacement and rotational speed can be calculated. These quadrature outputs let the host system determine the direction of rotation. To calculate speed and angular displacement, the encoder’s resolution – equivalent to the angular displacement represented by […]
Stress & Strain, Part 2: Implications for electronics
The mechanical strain induced on electronic components due to mechanical and thermal stress is an important aspect of their performance consistency and limitations; stress is also used to enable some materials to provide critical electronic functions. Part 1 of this FAQ looked at the basic principles and tests for material strain when stress is applied. […]
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 […]
