SPF5043Z
50 - 4000 MHz GaAs pHEMT Low Noise MMIC Amplifier
Qorvo's SPF5043Z 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 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.
