The difference between SMB and SMA connectors — frequency range, mechanical design, electrical performance, applications, and how to choose the right one for your RF system.

What is RF (radio frequency)? Learn the definition, frequency bands, properties, and the many uses of RF — from broadcasting and Wi-Fi to radar, medical imaging, and industrial heating.

What is an RF transfer switch? Learn how RF transfer switches work, the main types (coaxial, waveguide, latching), key specifications, and how they are used in redundancy, ATE, and broadcast systems.

How to extend the operating lifespan of electromechanical RF switches. Practical guidance on cold switching, derating, contact wear, environment, and maintenance for coaxial and waveguide RF switches.

RF attenuator power ratings explained — average, peak, and pulsed power handling, derating strategies, common failure modes, and best practices to avoid burning out your RF attenuator.

RF component selection for 5G and automated wireless testing — how to choose amplifiers, filters, antennas, switches, and connectors for FR1, FR2, mmWave, and ATE test systems.
