WIDE BANDWIDTH AMPLIFIER C6438-01 PRELIMINALY DATA JUN. 1999 C6438-01 is a wide bandwidth, DC to 50 MHz, amplifier. While providing the photomultiplier tube output current directly to C6438-01 input connector, it provides the voltage output signal in the conversion coefficient of 25 mV/1 A. It can be used as a wide bandwidth amplifier not only for a photomultiplier tube but also for other detectors. FEATURES Wide Bandwidth: DC to 50 MHz Rise Time: 7 ns Typ.
