SPF5043Z

SPF5043Z ® 50 MHz to 4000 MHz Low-Noise Amplifier General Description The SPF5043Z is a high-performance GaAs pHEMT MMIC LNA designed for operation from 50 MHz to 4000 MHz. The on-chip active bias network provides stable current over temperature and process threshold voltage variations. The SPF5043Z 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. The high maximum input power specification makes it ideal for high dynamic range receivers.
