GENERAL DESCRIPTION
The SPT104 linear amplifier represents a significant ad-
vance in linear amplifiers. Proprietary design techniques
have yielded an amplifier with 14dB of gain and a –3dB
bandwidth of DC to 1100MHz. Gain flatness to 750MHz of
±0.4dB 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 opera-
tion. 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 combine to produce an ampli-
fier well suited to many communications applications. With a
1.1GHz bandwidth, the SPT104 can handle the fastest digi-
tal 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 communications systems.
These same characteristics make the SPT104 an excellent
choice 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/bipolar
transistor technology, and is available in the following ver-
sions:
