SPF5189Z Low-Noise RF Amplifier - 50-4000MHz

Add a compact preamplifier stage to a compatible radio-receiving project. This SPF5189Z low-noise RF amplifier module is intended for weak-signal amplification, with a listed 50-4,000 MHz range that covers a broad selection of receiving applications.

✅ Amplify weak received signals - The LNA provides an amplification stage ahead of downstream receiving circuitry.

✅ Work across a broad RF range - The listed frequency coverage supports projects in several receiving bands.

✅ Fit a small electronics layout - The approximately 34 × 25 mm board suits compact project assemblies.

Develop the Front End of Your Receiver

When building a receiver chain, the first amplification stage deserves attention because it handles the incoming signal before later processing. This module gives you an LNA building block to evaluate within that chain.

Place it within a design that provides the correct power, impedance matching and signal levels. More gain is not automatically better in every location, particularly around strong signals, so evaluate the complete receiver setup for your intended application.
