RF Mixers

A RF Mixer, also known as a frequency mixer or a hybrid mixer, is a type of nonlinear electrical circuit element that can be used to mix two different frequencies together. The MAX9982ETP+T is a high performance, broadband, IF, Bias voltage-variable RF mixer designed specifically for use in a wide range of communication and aerospace/defense applications. This product\'s advanced design and low insertion loss makes it suitable for use in a variety of situations, including base station radio, cellular, reconnaissance, critical aircraft and missile guidance systems, satellite communication systems, and ground station radio applications.

Application Field

The MAX9982ETP+T RF mixer offers a variety of features that make it an ideal solution for applications where high input sensitivity and output dynamic range are desired. This product is well suited for use in frequency conversion, frequency synthesizers, intermediate frequency (IF) up- and down-converters, and satellite communications. It is also suitable for use in applications such as frequency hopping reconnaissance systems, ground-based missile guidance systems, and aircraft avionics systems. Furthermore, this product can be used in applications such as frequency hopping radio systems and in other applications requiring reliable, linear, low-noise, and broadband mixing performance.

Working Principle

When two different radio frequency (RF) signals are applied simultaneously to an RF mixer, the resulting signal is composed of two separated components at different frequencies: one at the sum frequency and one at the difference frequency. This output signal can then be filtered and amplified to pass through other components in an electronic circuitry, or it can be used directly in applications such as sound reproduction or transmission systems. The mixer works by allowing the two input signals to combine non-linearly, producing a new signal that has both the sum and the difference of the frequencies applied to the input. The amount of power transmitted or received by the mixer depends on the amplitude of the two inputs, as well as the amount of power transferred.

The MAX9982ETP+T operates in two different biasing configurations, low voltage and high voltage. The low-voltage configuration boosts the mixer\'s sensitivity while maintaining low spurs and harmonic content. The high-voltage configuration enhances the dynamic range of the mixer, providing a linear response to large signal amplitudes. The MAX9982ETP+T also utilizes a combination of precision matching and low-noise design techniques to ensure that it is able to deliver excellent performance in both low-noise and high-dynamic range applications.

The MAX9982ETP+T is a high-performance, high-reliability RF mixer device that can be used in a wide range of communication and aerospace/defense applications. Its high input sensitivity and output dynamic range make it suitable for use in a variety of situations, including base station radio, cellular, reconnaissance, critical aircraft and missile guidance systems, satellite communication systems, and ground station radio applications.
