Maxim Integrated MAX2673EUA+ Low-Noise Amplifier

The MAX2673EUA+ from Maxim Integrated is a high-performance, low-noise amplifier (LNA) designed to enhance the signal quality and sensitivity of RF receivers. This component is particularly suitable for applications in GPS, Galileo, and GLONASS navigation systems, as well as for wireless communication devices that require a low noise figure and high linearity.

Key Features

• Frequency Range: The MAX2673EUA+ operates within the 1559MHz to 1606MHz frequency range, making it ideal for L1/L2 GPS bands and other similar navigation systems.
• Low Noise Figure: With a noise figure as low as 0.8dB, this LNA significantly improves signal-to-noise ratio, which is critical for maintaining the integrity of the received signals.
• High Gain: It offers a high gain of 17.5dB, which ensures that weak signals are amplified without compromising their quality.
• Adjustable Current: The device provides the flexibility to adjust the supply current from 1.8mA to 5mA, allowing designers to optimize the performance for specific applications.
• Integrated Filter: An integrated filter contributes to the suppression of out-of-band interference, which can degrade the performance of the navigation system.
• Small Package: The MAX2673EUA+ comes in a compact 8-pin µMAX package, which is advantageous for space-constrained designs.
