GENERAL DESCRIPTION
The KGF1521 is a high-performance GaAs FET small-signal amplifier for L-band frequencies that features low voltage operation, low current operation, low noise, and low distortion. The KGF1521 specifications are guaranteed to a fixed matching circuit for 3 V and 1.9 GHz; external impedance-matching circuits are also required. Because of its high 3rd-order intercept point, even at its low operating current, the KGF1521 is ideal as a small-signal amplifier for L-band personal handy phones, such as digital keying cordless phones that require low intermodulation properties.
