9306-P 1-GHz Preamplifier

The Model 9306-P 1-GHz Preamplifier is optimized for fast timing and counting applications with detectors that deliver pulses with ultra-fast rise times. An output rise time of 350 ps and a non-inverting gain of 100 make the Model 9306-P deal for use with microchannel plates, microchannel-plate photomultipliers, channeltrons, silicon diodes, fast photomultiplier tubes, and electron multipliers. The compact preamplifier case with captive power cord permits close coupling to the detector to minimize sensitivity to environmental noise. 

To preserve the ultra-fast rise time, the Model 9306-P is designed to accept and deliver signals on high-quality, 50-Ω coaxial cables with SMA connectors and 50-Ω terminations. The input is ac-coupled, with a 50-Ω input impedance, and is protected to a maximum of ±1 V. Two identical outputs are provided for convenient, simultaneous connection to two different instruments. Both outputs are ac-coupled, short-circuit protected, and capable of driving pulse amplitudes from 0 to -2 V into 50-Ω loads. 

The Model 9306-P 1-GHz Preamplifier derives its +24-V dc power from a NIM module or power supply via the captive power cord and standard, 9-pin, D connector. The Model 4002P Portable Power Supply and most NIM amplifiers provide the required power on a compatible preamplifier power connector.

    PERFORMANCE  All specifications are measured with a pulser having a pulse width of 2 ns FWHM, and a rise time of 150 ps.  Where significant, the measurement is corrected for the rise times of the pulser, coaxial cable, and oscilloscope.  The specifications are identical for OUTPUTS 1 and 2.
    GAIN Nominally 100 (50 to 150), non-inverting, into a 50-Ω output load.
    OUTPUT RISE TIME Typically 350 ps.
    BANDWIDTH (3 db) Typically 100 kHz to 1 GHz.
    NOISE <100 µV rms equivalent input noise over the full bandwidth.
    INPUTS AND OUTPUTS  
    INPUT SMA input connector  with 50-Ω input impedance (ac-coupled) and a 10-kΩ resistance to ground.  Input protected to a maximum of ±1 V.
    OUTPUT 1 SMA output connector provides a linear output range from 0 to -1.75 V and a maximum output of -2 V into a 50-Ω load.  Output impedance is 50-Ω, ac-coupled, and short-circuit protected. The unused output must be terminated with a 50-Ω load for proper operation of the other output.  An optional SMA 50-Ω terminator is available for this purpose.
    OUTPUT 2 Indentical to OUTPUT 1.
    POWER Input power is supplied through a captive cable (lenght:3 m) with a standard preamplifier power connector (9-pin D type).  Compatible with instruments that provide a preamplifier power connector. 
    ELECTRICAL AND MECHANICAL
    POWER REQUIRED +24 V at 200 ma.  Captive power cord with standard 9-pin D connector derives power from any instrument equipped with the standard preamplifier power plug (e.g., spectroscopy amplifiers, 4002P Portable Power Supply, 9307-P pico-TIMING Discriminator, etc.)
    WEIGHT Net 0.2 kg (0.4 lb)
    Shipping 1.1 kg (2.4 lb)
    DIMENSIONS Alumimum housing9.5 X 6.4 x 2 cm (3.75 X 2.5 X 0.8 in.).
    OPTIONAL ACCESSORIES The Model 9306-P is designed for use with 50-Ω coaxial signal cables having SMA connectors.  The desired optional cables and adapters can be selected from the ordering information.  To avoid degradation of the 350-ps rise time through long signal cables, the total length of the input and output signal cables should be ≤1.7 m.  If one of the outputs is not used, it must be loaded with an SMA50 terminator.

    The Model 9306-P should be used with the Model 9307-P pico-TIMIMG™ Discriminator for optimum time resolution with ultra-fast detectors.
