Measuring a slight 3.0 x 2.0 x 0.58mm, […]
Wide-band instruments in the 5G Era
by David Hall, Principal Product Manager, RF and Wireless Communications, National Instruments, Corp. Just a decade ago, signal analyzers with 20 MHz of instantaneous bandwidth were considered state-of-the-art. Within a decade, signal analyzers with no less than 2 GHz of bandwidth will likely be entry-level devices. Clearly there’s a trend toward signal analyzers supporting wider […]
How to sniff out EMC problems
by Alan Lowne, President, Saelig Co. Inc. It pays to do preliminary studies before sending products off to the test lab for electromagnetic compatibility problems. An engineer in a relatively small company usually must rely on experience and tribal knowledge to design a product that is electromagnetically compatible (EMC) with other equipment. Many designers and […]
How to spec inductive coils
by Michael Harper, Coil Experts, LLC It pays RF designers to know a few things about the way coil-winding houses fabricate coils. Inductive coils are ubiquitous in any kind of RF or wireless circuit. But some of the tiny coils that characterize RF work can be challenging to produce. Custom coil designs often get sent […]
Wireless charging for your coffee maker
by Leland Teschler, Executive Editor, @DW_LeeTeschler Today’s average teenager has never seen a dial telephone. It looks as though cords that plug into ac outlets will soon look just as strange to high schoolers. That’s because wireless charging may become ubiquitous enough to make ac power cords obsolete for most kinds of electrical equipment rather […]
NXP Introduces World’s First RAIN RFID Tag
NXP Semiconductors N.V. (NASDAQ: NXPI) announced the introduction of its latest UCODE product, UCODE DNA, the world’s first UHF (ultra-high frequency) RAIN RFID tag IC to combine long-range read performance with cryptographic authentication. With this new tag IC developers no longer have to choose between contactless performance and the need for security in their applications; […]
How to use charge amplifiers
A charge amplifier is not the most common type of amplifier, but very useful in the right circumstances, it is really a current integrator which produces a voltage output proportional to the integrated value of the input current. This is useful when the sensor is capacitive such as a piezo device which could be a […]
Highly integrated IO-Link® temperature sensor
Maxim Integrated’s IO-Link smart temperature sensor reference design lowers cost and increases uptime for industrial control and automation. Designers can save power, cost, and space with the MAXREFDES42# IO-Link temperature sensor reference design (RD) from Maxim Integrated Products, Inc. (NASDAQ: MXIM). The new MAXREFDES42# IO-Link resistance temperature detector (RTD) joins the company’s portfolio of other […]
