An entire industry perked up its ears when Qorvo announced QSPICE™ in July 2023, and for good reason. This free circuit simulation software is built specifically to serve analog and power designers and is poised to save companies countless hours and thousands of dollars by reducing design time. How did Qorvo come to offer their own flavor of the popular SPICE simulation tool, and what does this mean for design engineers? This article discusses the history of SPICE, how QSPICE supports Qorvo’s growing silicon carbide (SiC) power management portfolio, and the advantages of SiC technology. First, let’s start with a little…

What made you select the Nuvotronics wideband 90-degree hybrid coupler family? How are these products different from others on the market? My August Expert Product Pick is a family of three products which I believe are going to prove invaluable to those designing next generation electromagnetic warfare (EW) and electronic countermeasure (ECM) systems. Cubic Nuvotronics has recently released three wideband 90-degree hybrid couplers: the PSC18H17S 2–18 GHz, PSC18H07S 6–18 GHz, and the PSC50H08S 18–50 GHz devices. All exhibit excellent electrical characteristics in small form factor packages utilizing Nuvotronics’ Polystrata® additive manufacturing technology. Polystrata devices are fabricated in copper and utilize…
What made you select MRC Component’s SoftProtector® Cores to feature? How does the product family differentiate from others/what value does it offer? MRC Components SoftProtector® Cores are highly effective at mitigating harmful interference currents caused by modern high-power frequency converter operated systems, especially those operating at very high switching frequencies. Integrating an easy-to-retrofit SoftProtector Core solution minimizes instances of unexpected system failures and communication issues while ensuring that motor bearings, sensors, and motor terminals are protected. SoftProtector Cores enable system operation with a calculable maintenance cycle as they absorb and convert damaging high-frequency interface current into thermal energy that can…

What made you select Qorvo’s ACT43750 as a product to feature? How does the ACT43750 differentiate from its competitors? The Qorvo ACT43750 is a highly-integrated drain switch and negative gate voltage regulator PMIC that enables ultra-fast RF GaN PA drain switching. The device provides programmable gate bias voltage, a fast drain switch response of 30ns (typ), auto bias sequencing, configurable IQ (drain) setpoint, and auto-calibration to compensate for the effects of temperature/aging. When used with the ACT43850 RFPoL buck regulator and constant current capacitor charger ICs, the chipset forms a complete compact power supply system. This system is designed for…
Article By Microchip Product Manager Baljit Chandhoke RF systems need power amplifiers (PAs) to deliver linear efficient high output power. As systems move to higher-order modulation schemes such as 64/128/256 Quadrature Amplitude Modulation (QAM), they also must deliver high linearity and efficiency in denser environments with stringent peak-to-average power ratio (PAPR). This performance is critical in Aerospace & Defense (A&D), Satellite Communications (Satcom) and 5G Communications. A new generation of Gallium Nitride (GaN) on Silicon Carbide (SiC) Monolithic Microwave Integrated Circuits (MMIC) PAs offers a solution to these challenges with the highest power density to generate high linear output power with high…
