KGF1522
Small-Signal Amplifier
GENERAL DESCRIPTION
The KGF1522 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
KGF1522 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 KGF1522 is ideal as a signal amplifier for L-band personal
handy phones, such as digital keying cordless phones that require low intermodulation proper-
ties.
FEATURES
鈥?Low voltage and low current operation: 3 V, 5 mA (max.)
