The Radio Data System: FM radio adds features to stay viable, part 1
Broadcast FM radio has extended its user-friendly capabilities through the addition of embedded, backward-compatible functionality which adds text and even graphics to the radio display. From the late 1920s and for decades afterward, AM-based broadcast radio was the primary real-time mass media in the US and the world. In the AM band (550 kHz to […]
94 GHz elastomer socket for 300 W device
Ironwood announced a 94 GHz elastomer socket for 300 W GPA3184. With lever operated mechanism, users can quickly and easily socket a 0.92 mm pitch, 56 x 45mm size with 3184 contacts on any development platform.

FAQ on fractal antennas, Part 2
Antennas based on fractal mathematics offer some significant advantages but also some controversy. The first part of this article looked at the basic concept and history of fractals. This part looks at the relationship between fractals and antennas. Q: All this fractal discussion is interesting, but what does it have to do with antennas? A: […]
FAQ on fractal antennas, Part 1
Antennas based on fractal mathematics offer some significant advantages but also some controversy Although all antenna designs are derived from either the basic dipole or monopole/ground-plane configurations, there are almost countless antenna variations in use (Figure 1). Each one offers a different combination of key attributes such as center frequency, bandwidth, bandwidth, side lobes, front-to-back […]
Instrumentation amps measure small voltages in EVs
Diodes Incorporated introduces a series of high-precision current shunt monitors designed to measure small sense voltages across a wide common-mode voltage range in electric vehicles (EVs): the ZXCT21xQ family. Automotive applications for these single-stage instrumentation amplifiers include current sensing of load/rail currents in brushless DC (BLDC) motor controllers, e-compressors, high-power DC-DC converters, on-board chargers (OBC), battery […]
