Proprietary design techniques have yielded an amplifier with 14d B of gain and a - 3d B bandwidth of DC to 1100MHz. Gain flatness to 750MHz of ±0.4d B coupled with excellent VSWR and phase linearity gives outstanding pulse fidelity and low signal distortion. Designed for 50Ω systems, the SPT104 is very easy to use, requiring only properly bypassed power supplies for operation. This translates to time and cost savings in all stages of design and production. Fast rise time, low overshoot and linear phase make the SPT104 ideal for high-speed pulse amplification. These properties plus low distortion bine to produce an amplifier well suited to many munications applications. With a 1.1GHz bandwidth, the SPT104 can handle the fastest digital traffic, even when the demodulation scheme or the digital coding format requires that DC be maintained. It is also ideal for traditional video amplifier applications such as radar or wideband analog munications systems. These same characteristics make the SPT104 an excellent choice for use in fiber optics systems, on either the transmitting or receiving end of the fiber. The low group delay distortion insures that pulse integrity will be maintained. As a photomultiplier tube pre-amp, its fast response and quick overload recovery provide for superior system performance. The SPT104 is constructed using thin film resistor/bipolar transistor technology, and is available in the following versions: SPT104AI - 25 °C to +85 °C 14-pin double-wide DIP Basic Circuit Diagram Equivalent Circuit...
