www.fairchildsemi.com KH104 DC to 1.1GHz Linear Amplifier Features s s s s s s General Description The KH104 linear amplifier represents a significant advance 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 KH104 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 KH104 ideal for high speed pulse amplification. These properties plus low distortion combine to produce an amplifier well suited to many communications applications. With a 1.1GHz bandwidth, the KH104 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 communications systems. These same characteristics make the KH104 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 preamp, its fast response and quick overload recovery provide for superior system performan...
