Should You Remove Ground Below Impedance Matching Networks? Should You Remove Ground Below Impedance Matching Networks? Impedance matching networks in a PCB layout might need to have ground cleared from them. We’ll explore when to remove ground in this short guide.
SMA Edge Connector Transitions in an RF PCB SMA Edge Connector Transitions in an RF PCB SMA edge connector footprints sometimes require ground clearance below the connector’s coaxial pin. We’ll show why this can arise and how to qualify the need for ground clearance.
Knee Frequency Derivation Where Does the Knee Frequency Formula Come From? The knee frequency has nothing to do with signal bandwidth, but it has everything to do with channel bandwidth.
How to Design a Bias Tee for a Power Amplifier How to Design a Bias Tee for a Power Amplifier Bias tees are used in some RF systems to separate AC and DC power along a particular line. Learn more about bias tee design in this article.
Pole-Zero Analysis and Transient Analysis in Circuit Design Pole-Zero Analysis and Transient Analysis in Circuit Design Here’s how pole-zero analysis as part of transient analysis can help you identify underdamped responses, zero-output frequencies, and much more.
