Infineon BAT15-04W: Schottky Diode for High-Frequency and Mixer Applications

The Infineon BAT15-04W is a surface-mount silicon Schottky diode pair specifically engineered for high-frequency applications, particularly in mixers, detectors, and multipliers. Its design focuses on delivering exceptional performance in RF and microwave circuits where low loss, fast switching, and high reliability are paramount.

A key advantage of the BAT15-04W is its very low forward voltage and extremely fast switching characteristics. These traits are fundamental for minimizing power loss and enabling efficient operation at very high frequencies, making it an ideal choice for sensitive communication equipment. The diode pair is configured in a common-cathode arrangement within a single SC-79 package, which saves valuable PCB space and ensures excellent symmetry—a critical requirement for balanced mixer designs that demand precise performance from both diodes.

This component excels in mixer and detector applications up to the Ku-band and beyond. Its low noise figure and high conversion efficiency make it suitable for critical roles in satellite receivers, radar systems, point-to-point radio links, and test and measurement instrumentation. The robust ceramic package provides strong environmental protection and reliable performance under demanding operating conditions.

ICGOOODFIND: The Infineon BAT15-04W stands out as a superior choice for RF designers, offering an optimal blend of low capacitance, fast switching speed, and integration in a miniature package. It is a critical enabler for high-performance, high-frequency systems where efficiency and signal integrity cannot be compromised.
