New Tech Tuesdays: 3 Small RF Passive Components That Keep Circuits Intact

On gegužė 17, 2021 in All, Circuit Protection, Computing, General, Maker, New Tech Tuesdays, RF by Tommy Cummings

RF passives might not be flashy, but they play an essential role in RF and microwave circuits. New Tech Tuesdays examines AVX inductors, Murata capacitors, and Vishay resistors, three new-to-market RF passives for design engineers to consider.

Your Microwave Oven May Soon Become Obsolete

On gegužė 30, 2017 in All, Power, RF by Barry Manz

Microwave ovens use magnetrons because they're cheap and robust. But RF power transistors are overcoming the limitations that keep them out of microwaves. Solid state power could transform the microwave into a full-fledged cooking appliance.

Last Call for Magnetron-Powered Microwave Ovens?

On gruodis 5, 2014 in RF by Barry Manz

When in 1945 Raytheon’s engineer Percy Spencer accidently discovered the potential of RF energy for heating food (or in Spencer’s case, for melting a chocolate bar in his pocket), the device generating that energy was a magnetron. Sixty years later, this venerable “vacuum electron device” is still powering everyone’s microwave ovens, making it the only consumer product still using a vacuum tube rather than a semiconductor for any purpose. However, this last bastion of vacuum tubes in consumer electronics may soon be relegated to history now that RF power transistors have achieved the required RF output power, efficiency, and ruggedness required to replace them.

Wireless in 2014: The Industry at Mid-Year

On birželis 26, 2014 in IoT, RF by Barry Manz

As members of the RF and microwave industry make their annual pilgrimage to IMS 2014 (this year in Tampa), I offer my opinion on the industry’s overall health at mid-year. Fortunately, it appears that it’s going to be hot in Tampa in more ways than one. Just how hot depends on many factors, many of them company-specific, so there’s no single answer to “How’s business?” Nevertheless, a realistic approach with this blog is to look at key markets in the wireless industry.

The “Death of the Downconverter”? Not Just Yet

On balandis 2, 2014 in RF by Barry Manz

The impact of converting analog signals to digital form is one of the greatest advances the electronics industry has ever achieved. Although today almost every consumer, industrial, commercial, and military system depends on this capability, one of the last remaining outliers is directly converting analog signals at microwave frequencies into digital data streams without using large amounts of intervening microwave hardware (i.e., downconverters).
