Bird 8890-300SC13 2.5 KW, DC to 28 MHz Precision RF Load

Bird 8890-300SC13 2.5 KW, DC to 28 MHz Precision RF Load 8890-300SC13, 13.56 MHz Ultra Stable Oil-Dielectric RF Termination For maximum process repeatability and consistency, modern plasma applications require precise RF power regulation and control. A key component in ensuring accurate & repeatable RF power delivery to the chamber is calibration, regulation & monitoring of the RF generator. Bird now offers ultra-stable, low VSWR loads for quick and precise measurement of generator power output when used with precision power sensors such as the Bird 4020 series. The 8890-300SC13 not only provide low VSWR but also less than 0.1 dB total change in VSWR at process critical frequencies. There is no need for load warm-up or risk of repeatability due to calibration for different lengths of time. This can minimize the errors associated with this calibration and control one of the more critical process variables.
