SIM914 - Stanford Research Systems Preamplifiers

Get Quote

  • Model: SIM914
  • Manufactured by: Stanford Research Systems
  • High end frequency limit: 350.0MHz
  • Gain: 14 dB
  • Noise Figure: n/a
  • Extra Specifications: BJT Voltage Preamplifier

The SIM914 350 MHz Preamplifier contains two wide-bandwidth, 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 SIM914s can be cascaded without creating oscillation problems.  Input clamping gives a 3 ns recovery time from a 10´ overload.

Wde bandwidth, along with and 50 W input and output impedance, ensures a linear phase response across the entire frequency range, preserving pulse shapes

  • DC to 350 MHz bandwidth
  • Two independent amplifier channels
  • Voltage gain of 5 (14 dB) per channel
  • 3 ns overload recovery
  • Excellent phase linearity
