Product Overview

The SPF5043Z is a high-performance GaAs pHEMT MMIC low noise amplifier designed for 50MHz to 4000MHz wideband applications. With on-chip active bias network and integrated matching circuits, it delivers ultra-low noise figure, high linearity, and single-supply operation, making it ideal for high dynamic range receivers, wireless communication systems, and RF front-end modules.

Key Features

• Ultra-Low Noise Figure: Only 0.8dB at 900MHz ensures high-fidelity signal amplification.
• High Linearity Performance: OIP3 of 35dBm at 1900MHz supports large dynamic range signal processing.
• Wideband Coverage: Stable operation from 50MHz to 4000MHz for multi-standard communication systems.
• Simplified Single-Supply Design: 5V single-supply with integrated matching networks reduces PCB complexity.
• Industrial-Grade Reliability: Operates from -40°C to +85°C, suitable for harsh environments.
