What made you select the Qorvo UJ4SC075009B7S as product to feature? How does this product differentiate from others and what value does it offer?Qorvo’s UJ4SC075009B7S is an AEC-Q101 Qualified 750 V, 9 mΩ Gen 4 SiC FET. Its distinctive stacked cascode circuit configuration integrates a normally-on SiC JFET alongside a Si MOSFET, resulting in a normally-off SiC FET device. The stacked design also creates more space for larger die allowing for lower RDS(on) performance in the same package size, and the 750V rating offers enhanced voltage transient margin over similar 600 – 650V rated devices. The gate-drive characteristics allows for…

Traditional base-station RF power amplifiers (Figure 1) utilize a variety of different technologies and operating conditions to balance different performance parameters. One of the most common challenges in achieving optimal performance involves finding the balance between linearity and efficiency. The key drivers for balancing linearity with efficiency, in order of importance, are: Determining between GaN, LDMOS, or SiGe as the optimal technology for your device. The specific class of device operation, ranging from Class A, AB, C, or E. Considering the configuration of circuit topology (Single-Ended, Push-Pull, or Doherty). The strategic management of back-off ratios from the P1dB compression point.…

What made you select the XMA Cryogenic Attenuators as featured products? How do these products offer value ? The Cryogenic line of Attenuators from XMA is the epitome of purposeful design. By understanding how the resistive attenuation generates heat in the Quantum Computing environment of millikelvin temperatures, they have chosen materials and structures which disperse the heat through attenuator body rather than the coaxial lines. These components dissipate the generated heat into the immediate environment rather than off-loading it into the coaxial cables to be carried to other chambers and interfering with the Quantum Processor.
