How To Bypass The ADF4371 And ADF4372 VCOs Autocalibration

The ADF4371 and the ADF4372 are wideband synthesizers with integrated voltage controlled oscillators (VCOs) that use autocalibration to choose the appropriate core select, band select, and bias level calibration values to lock the device.

Glass Sidewall Packages Provide Performance For RF Applications

Glass sidewall packages achieve highest levels of hermeticity for hardware in space vacuums and extreme temperatures. Compared to ceramic, they deliver better RF performance thanks to their lower dielectric constant.

Best Practices For Maximizing The Performance Of Our Surface-Mount Filters

Knowles Precision Devices DLI microstrip bandpass filters offer innovative filter topologies yielding excellent performance in a small footprint when fabricated on high DK temp stable ceramic substrate materials. To ensure optimal performance, this article discusses best practices and resources.

EM Simulation Of 140 GHz Antenna Array For 6G Wireless Communication

In this example, a 140 GHz slot antenna array excited by a substrate integrated cavity is demonstrated for use in wireless communications.

Spectral Regrowth: Stay In Your Lane

For digitally modulated signals transmitted via power amplifiers, how far “our car” has crossed into the neighboring lane is defined as spectral regrowth. This article discusses spectral regrowth and how NuWaves' amplifiers are designed for high-performance spectral regrowth in automotive applications.

Power Supplies — What’s Better: Custom Or COTS?

When sourcing power supplies for military and commercial applications, system design engineers must choose between commercial off-the-shelf (COTS) or custom products. This article clarifies the misunderstandings of each, including delivery timelines, ease of integration, and real-world performance.
