Maxim Integrated's MAX19995ETX+: Dual, Downconversion Mixer with LO Switch

The MAX19995ETX+ from Maxim Integrated is a high-performance, dual, downconversion mixer that offers a comprehensive solution tailored for demanding RF applications. This advanced component is designed to function within the 1700MHz to 2200MHz frequency range, making it a perfect fit for a variety of wireless communication systems such as LTE, WCDMA, and multicarrier GSM base stations.

One of the standout features of the MAX19995ETX+ is its integrated local oscillator (LO) switch, which simplifies the design and reduces component count in complex systems that require multiple LO inputs. The device's exceptional linearity and noise performance are key to maintaining signal integrity, thereby ensuring high-quality signal processing in the RF signal chain.

The mixer is housed in a compact, 36-pin thin QFN-EP (6mm x 6mm) package, which not only saves valuable board space but also offers enhanced thermal performance. The MAX19995ETX+ operates over the extended temperature range of -40°C to +85°C, ensuring reliable performance across various environmental conditions.

Key specifications of the MAX19995ETX+ include:

• High linearity with an input IP3 of 24.5dBm
• Low noise figure of 9.7dB
• Conversion gain of 7.9dB
• Integrated LO switch with isolation of 42dB at 1960MHz
• Single-ended RF and LO ports for ease of interfacing
• Dual differential IF outputs supporting a wide frequency range

The device also features a robust on-chip LO buffer, which reduces the need for external components and simplifies the LO path design. This is complemented by the integrated balun structures that enable single-ended RF input, further reducing external component requirements and simplifying the board layout.

Whether you're designing for base station transceivers, point-to-point radios, or satellite communications, the MAX19995ETX+ provides a reliable and efficient solution for your downconversion needs. Maxim Integrated's commitment to quality ensures that you receive a product that not only meets but exceeds industry standards for performance and reliability.
