How many types of radar are there?

May 17, 2022 By Jeff Shepard

Radio detection and ranging (radar) uses reflected radio waves to detect and determine the distance, angle, and velocity of objects relative to the radar system. A basic radar system consists of a transmitter producing electromagnetic waves in the radio or microwave spectrum (these can be pulsed or continuous), a transmitting antenna, a receiving antenna (often […]

What is characteristic impedance?

May 14, 2022 By David Herres Leave a Comment

We speak of 50- or 75-Ω coaxial cable. The novice wonders if these numbers apply to a given length, say 100 ft. Could you connect an ohmmeter to one end of the cable and expect to get that reading with or without the conductors shunted at the far end? The answer is absolutely not. The characteristic impedance […]

650 V SiC MOSFET is first in TO-LeadLess package

May 11, 2022 By Redding Traiger

onsemi announced the world’s first TO-Leadless (TOLL) packaged silicon carbide (SiC) MOSFET at PCIM Europe. The transistor addresses the rapidly growing need for high-performance switching devices that are suitable for designs with high levels of power density. Until recently, SiC devices had been supplied in D2PAK 7-lead packages which required significantly more space. With a footprint of […]

MOSFETS feature low on resistance for high power density

May 10, 2022 By Redding Traiger

STMicroelectronics’ STPOWER MDmesh M9 and DM9 N-channel super-junction multi-drain silicon power MOSFETs are ideal for switched-mode power supplies (SMPS) in applications from data-center servers and 5G infrastructure to flat-panel televisions. The first devices to be launched are the 650V STP65N045M9 and the 600V STP60N043DM9. Both have very low on-resistance (RDS(on)) per unit area, which maximizes power density and permits compact system dimensions. Each has the […]

What is “orthogonal”? (Part 2): signal space

May 10, 2022 By Bill Schweber

The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. The formal definition of orthogonal signals does not necessarily mean that they are unrelated or uncorrelated, although that is how the term is often used in casual “engineering speak.” Formally, two vectors are orthogonal if their dot product is […]

What is “orthogonal”? (Part 1): mechanical design 

May 9, 2022 By Bill Schweber

The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. I was chatting the other day with a non-technical friend and said something like, “Oh, that won’t happen. Those two things are orthogonal.” My friend looked at me and replied with a “huh?” and he was right to do […]
