GaN RF switch delivers 20 W
Built on a wide-bandgap GaN HEMT process, Teledyne’s TDSW84230EP reflective SPDT switch covers 30 MHz to 5 GHz, handling 20 W of continuous power. It is intended to replace PIN diode-based RF switches commonly used in the RF front ends of…
Reference design highlights GaN for motor drives
EPC offers a GaN-based motor drive inverter reference design for industrial and battery-powered applications. The EPC91200 demonstration board, built for 3-phase brushless DC motors, integrates the EPC2305, a 150-V, 3.0-mΩ GaN FET.
With a…
100-V MOSFETs cut on-resistance
Renesas 100-V N-channel MOSFETs leverage an improved wafer manufacturing process with split gate technology, reducing on-resistance (RDS(on)) by 30%. The REXFET-1 process also cuts total gate charge (Qg) by 10% and gate-to-drain charge (Qgd)…
Add one resistor to allow DAC control of switching regulator output
Whether its buck, boost, or buck/boost, internal or external switch, milliamps or tens of amps, a literal cornucopia of programmable output switching regulator/converter chips are commercially available. While the required external Ls and Cs…
How TMDs can transform semiconductor manufacturing
While semiconductors remain in high demand, electronics engineers must stay abreast of associated developments that could eventually affect their work. Case in point: significant advancements in transition metal dichalcogenides (TMDs).
These…
Tamron’s TAP-in Console: A nexus for camera lens update and control
Camera lenses were originally fully mechanical (and in some cases, still are; witness my Rokinon Cine optics suite). The user manually focused them, manually set the aperture, and manually zoomed them (for non-fixed-focal length optics, that…
How neon lamps can replace LEDs in AC-powered designs
It’s not difficult to drive an LED indicator from the AC line, but it requires many active and passive components. It also poses safety challenges. EDN and Planet Analog blogger Bill Schweber explains how engineers can replace LEDs with neon…
Part 1: A beginner’s guide to the power of IQ data and beauty of negative frequencies
Editor’s Note: This is a two-part series where DI authors Damian and Phoenix Bonicatto explore IQ signal representation and negative frequencies to ease the understanding and development of SDRs.
Part 1 explains the commonly used SDR IQ signal…
The 2025 CES: Safety, Longevity and Interoperability Remain a Mess
Once again this year, I’m thankfully reporting on CES (formerly also known by its de-acronym’d “Consumer Electronics Show” moniker, although the longer-winded version is apparently no more) from the remote comfort of my home office.…
