Product Description
The SPF-5122Z is a high performance pHEMT MMIC LNA designed for
operation from 50MHz to 4000MHz. The on-chip active bias network pro-
vides stable current over temperature and process threshold voltage vari-
ations. 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. A
high maximum input power specification make it ideal for high dynamic
range receivers.
