SPF5122Z

SPF5122Z 50MHz to 4000 MHz, GaAs pHEMT Low Noise MMIC Amplifier SPF5122Z 50MHz to 4000MHz, GaAs pHEMT LOW NOISE MMIC AMPLIFIER Product Description The SPF5122Z is a high performance pHEMT MMIC LNA designed for operation from 50MHz to 4000MHz. The on-chip active bias network provides stable current over temperature and process threshold voltage variations. The SPF5122Z offers ultra-low noise figure and high linearity performance in a gain block configuration. Its single-supply operation and integrated matching networks make implementation remarkably simple. A high maximum input power specification make it ideal for high dynamic range receivers.
