SPF-5122Z Datasheet, PDF (1/6 Pages) SIRENZA MICRODEVICES – 400-3000 MHz, GaAs pHEMT Low Noise MMIC Amplifier

Product Description
The SPF-5122Z is a high performance pHEMT MMIC LNA designed for
operation from 400-3000 MHz. The on-chip active bias network provides
stable current over temperature and process threshold voltage variations.
The SPF-5122Z 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. High maximum
input power specification make it ideal for high dynamic range receivers.
