What are the key features of MAX2644EXT+T?

15dB gain SiGe LNA at 2.4GHz with high IP3 linearity enabling excellent dynamic range in crowded ISM-band RF environments
50Ω characteristic impedance with 5dBm maximum CW input power handling for robust front-end protection in wireless receivers
Ultra-compact 6-pin SC70 surface mount package minimizes PCB footprint in space-constrained 2.4GHz radio module designs

What is MAX2644EXT+T used for?

The MAX2644EXT+T is designed for 2.4GHz ISM-band receive chains in Bluetooth, Wi-Fi, and ZigBee modules where low noise figure and high linearity are critical. Its 15dB gain compensates for cable or filter insertion loss ahead of the RF mixer, and the SC70 package allows integration into miniaturized IoT dongles, industrial wireless sensors, and consumer wearable radio front ends.

Frequently Asked Questions

What gain and input power handling does the MAX2644EXT+T provide at 2.4GHz?

The MAX2644EXT+T delivers 15dB of small-signal gain at 2.4GHz with a maximum CW input power of 5dBm, making it suitable as a low-noise preamplifier in wireless receiver front ends. Its SiGe process achieves high IP3 linearity that limits distortion even when multiple 2.4GHz interferers are present in ISM-band environments.

For which wireless standards can the MAX2644EXT+T serve as the receive-path LNA?

The MAX2644EXT+T is optimized for 2.4GHz ISM-band protocols including Bluetooth Classic, Bluetooth Low Energy, IEEE 802.11b/g Wi-Fi, ZigBee (IEEE 802.15.4), and proprietary 2.4GHz FSK/OOK links. Its 50Ω input and output impedance simplifies PCB matching network design for any of these standards without retuning the bias network.

How does the SC70 6-pin package of the MAX2644EXT+T benefit RF board layout compared to larger packages?

The 6-pin SC70 package occupies roughly 2.0mm × 2.1mm board area, about 60% less than a SOT-23 package, reducing parasitic inductance and coupling between supply and RF pins. This smaller footprint shortens matching network trace lengths at 2.4GHz, improving gain flatness and noise figure predictability across production boards.

What supply voltage range does the MAX2644EXT+T require and how does it affect system integration?

The MAX2644EXT+T operates from a 2.7V to 5.25V supply range, covering both 3.3V and 5V digital rail voltages common in IoT and embedded systems. This flexibility eliminates the need for a dedicated LNA voltage regulator in most designs, reducing component count and board complexity while maintaining stable 15dB gain across the full voltage range.
