SPT104

The SPT104 linear amplifier represents a significant ad-vance in linear amplifiers.Proprietary design techniqueshave yielded an amplifier with 14dB of gain and a3dBbandwidth of DC to 1100MHz. Gain flatness to750MHz of±0.4dB coupled with excellent VSWR and phase linearity gives out pulse fidelity and low signal distortion.

Designed for 50Ω systems, the SPT104 is very easy to use,requiring only properly bypassed power supplies for opera-tion. This translates to time and cost savings in all stages ofdesign and production.

Fast rise time,low overshoot and linear phase make theSPT104 ideal for high-speed pulse amplification.Theseproperties plus low distortion combine to produce an ampli-fier well suited to many communications applications.With a1.1GHz bandwidth, the SPT104 can handle the fastest digi-tal traffic,even when the demodulation scheme or the digitalcoding format requires that DC be maintained. It is also idealfor traditional video amplifier applications such as radar orwideband analog communications systems.

These same characteristics make the SPT104 an excellentchoice for use in fiber optics systems, on either the transmit-ting or receiving end of the fiber. The low group delay distor-tion insures that pulse integrity will be maintained. As a pho-tomultiplier tube pre-amp, its fast response and quick
overload recovery provide for superior system performance.

The SPT104 is constructed using thin film resistor/bipolartransistor technology, and is available in the following ver-sions:SPT104AI 25 °C to +85 °C 14-pin double-wide DIP
