Product Summary

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 SPF5122Z ideal for high dynamic range receivers. The applications of SPF5122Z are: (1)Cellular, PCS, W-CDMA, ISM, WiMAX Receivers; (2)PA Driver Amplifier; (3)Low Noise, High Linearity Gain Block Applications.
