SIM914 Dual 350 MHz Preamplifier
The SIM914 350 MHz preamplifier contains two widebandwidth, DC-coupled amplifiers, each with a gain of
5 (14 dB). Its fast rise time, low noise, and excellent DC
accuracy make it an ideal instrument for amplifying signals
like those from photomultiplier tubes and photodiodes.
The gain stages of several SIM914 can be cascaded without
creating oscillation problems. Input clamping gives a 3 ns
recovery time from a 10× overload.
Wide bandwidth, along with 50 Ω input and output impedance,
ensures a linear phase response across the entire frequency
range, preserving pulse shapes.
