Maxim Integrated MAX9994ETP High-Linearity, Low-Noise Downconversion Mixer

The MAX9994ETP from Maxim Integrated is a state-of-the-art downconversion mixer designed to deliver exceptional performance in RF systems. This advanced component is ideal for applications requiring high linearity and low noise, such as in wireless infrastructure, point-to-point radio, and satellite IF receivers.

At the core of the MAX9994ETP is a double-balanced mixer that provides a high level of integration, reducing the need for external components. The device operates over a wide frequency range, with an RF frequency range of 1700MHz to 4000MHz and an LO frequency range of 1550MHz to 4000MHz, making it versatile for various communication bands.

This mixer boasts an outstanding third-order intercept point (IIP3) of 25.5dBm at 1900MHz, which ensures excellent linearity and dynamic range. It also features a low noise figure of 9.7dB at 1900MHz, contributing to the overall system sensitivity and performance. The conversion gain of 7.9dB at 1900MHz allows for robust signal processing without significant insertion loss.

The MAX9994ETP is designed with convenience in mind, supporting single-ended RF, LO, and IF ports to simplify PCB layout and reduce component count. It is also internally matched to 50 ohms, minimizing the need for external matching components and further streamlining the design process.

With an operating temperature range of -40°C to +85°C, the MAX9994ETP is suitable for deployment in a variety of environments. Its compact package, a 20-pin thin QFN with exposed paddle (5mm x 5mm), allows for efficient use of board space in space-constrained applications.

Maxim Integrated's commitment to quality and reliability is evident in the MAX9994ETP, making it an excellent choice for designers looking to enhance their RF systems with a high-performance downconversion mixer. Its combination of high linearity, low noise, and ease of use ensures that it will be a valuable component in any high-frequency signal chain.
