Trimmer Capacitor Considerations In Practice
6/3/2020
Trimmer capacitors are variable components used to calibrate RF circuits during manufacturing or servicing. These components allow for variable tuning — think oscillator frequency values or rise and fall times. Should values drift over the life of the device, trimmer capacitors can be recalibrated.

Filter Shape Factor And Selectivity
3/8/2019
This article discusses how a real-world filter’s deviation from ideal behavior needs to be quantified and that shape factor and selectivity are tools to use in this process. It touches on how both resonator Q and the filter order (number of resonators in a design) can influence a filter's behavior in the transition band.

Medical Imaging Quality Starts By Selecting The Right Components
MRI machines use a strong magnetic field and computer-generated radio waves to produce cross-sectional images. Thus, the quality of the MRI depends on field uniformity and the radio components inside.
