FROM THE EDITOR

The Transistor: From Vacuum Tubes To Digital Revolution

The transistor, invented at Bell Labs in 1947, replaced bulky vacuum tubes and enabled the miniaturization revolution that created modern electronics. It is one of the biggest inventions of the 20th century.

SPOTLIGHT ON PASSIVE & CONTROL COMPONENTS

How Thin-Film IPDs Advance Miniaturization And Performance

Integrated Passive Devices (IPDs) streamline electronics by combining components. Using thin-film technology, they enable miniaturization and help engineers achieve strict size, weight, and power goals.

INDUSTRY INSIGHTS

How To Save Time And Money Sourcing Switches For RF Applications

Being able to procure both EM switches and PIN diode switches from a single, U.S.-manufactured source provides increased flexibility and access to expertise for customers.

5G Mobile Network Testing Using A Passive Network Scanner

In Part One, we discussed why a dedicated scanner is necessary for accurate mobile network testing. This part explains the technical background and the setup of the measurements in FR1 and FR2.

Group Delay Engineering In RF Filters

RF filter design can be tricky, especially in mid-range frequencies where impedance matching and parasitics pose challenges. Explore the complexities and methods to engineer optimal group delay curves.
