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…

Introduction by Kirk BartonHow can a designer approach reducing oscillations and voltage spikes in semiconductor switches? Unwanted oscillations and voltage spikes in semiconductor switches can pose serious challenges and potentially compromise the overall operation of electronic circuits. The occurrence of oscillations can generate high-frequency noise, which in turn can interfere with the functioning of nearby electronic components. This can lead to signal distortion, reduced signal quality, and other related issues that can adversely affect the performance and reliability of the circuit. Voltage spikes generated during switching can cause damage to the semiconductor switch itself, as well as other connected electronic…
