KGF1521
Small-Signal Amplifier
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.
FEATURES
• Low voltage and low current operation: 3 V, 2.5 mA (max.)
• Specifications guaranteed to a fixed matching circuit for 3 V, 1.9 GHz
• Low noise figure: 1.8 dB (typ.) at 1.9 GHz
• High linear gain: 12.5 dB (typ.) at 1.9 GHz
• High output power: 1 dB compression point = 0 dBm (typ.) at 1.9 GHz
• Low distortion: 3rd-order intercept point = 12 dBm (typ.) at 1.9 GHz
• Self-bias circuit configuration with built-in source capacitor
• Package: 4PSOP
