9306 1-GHz Preamplifier

Specifications

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-W 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-W input impedance (ac-coupled) and a 10-kW 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-W load. Output impedance is 50-W, ac-coupled, and short-circuit protected. The unused output must be terminated with a 50-W load for proper operation of the other output. An optional SMA 50-W terminator is available for this purpose.

OUTPUT 2 Identical to OUTPUT 1.

POWER Input power is supplied through a captive cable (length: 3 m) with a standard preamplifier power connector (9-pin D type). Compatible with ORTEC 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 ORTEC instrument equipped with the standard preamplifier power plug (e.g., spectroscopy amplifiers, 4002P Portable Power Supply, 9307 pico-TIMING Discriminator, etc.).

WEIGHT
Net 0.2 kg (0.4 lb).
Shipping 1.1 kg (2.4 lb).

DIMENSIONS Aluminum housing 9.5 X 6.4 X 2 cm (3.75 X 2.5 X 0.8 in.).

OPTIONAL ACCESSORIES

The Model 9306 is designed for use with 50-W 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 should be used with the Model 9307 pico-TIMING™ Discriminator for optimum time resolution with ultra-fast detectors.
