The MAX19999ETX+T from Maxim Integrated is a state-of-the-art dual downconversion mixer designed to provide exceptional linearity and noise performance in a compact package. This device is tailored for applications in the 1700MHz to 2200MHz frequency range, making it an ideal choice for wireless infrastructure deployments in the LTE, WCDMA, and GSM/EDGE bands.

Key Features:

• High Linearity: With an input IP3 (third-order intercept point) of 25.5dBm at 1960MHz, the MAX19999ETX+T delivers outstanding linearity, ensuring minimal distortion in complex signal environments.
• Integrated LO Buffer: The inclusion of an on-chip LO (local oscillator) buffer amplifier simplifies design and reduces component count, while providing a stable and consistent LO signal to the mixer cores.
• Low Noise Figure: A low noise figure of 9.7dB at 1960MHz enhances the sensitivity of the receiver chain, allowing for the detection of weaker signals with higher fidelity.
• Dual Mixer Design: The dual mixer configuration enables simultaneous downconversion of I (In-phase) and Q (Quadrature-phase) signals, critical for modern digital communication systems that utilize complex modulation schemes.
• Wideband IF: The device supports a wide intermediate frequency (IF) range, accommodating various system architectures and simplifying integration into diverse designs.

Applications:

• Base Station 2G, 3G, 4G Infrastructure
• Point-to-Point and Point-to-Multipoint Microwave Links
• Wireless Local Loop
• MMDS and Wireless Cable (2.5GHz)

The MAX19999ETX+T is available in a compact, 36-pin thin QFN-EP (6mm x 6mm) package, which is optimized for thermal performance and space-constrained applications.
