The MAX2685EEE+ is a one-chip mixer solution that increases IC integration and customizability to lower PCB area and cost. It offers a wide range of features, including IP3 noise figure, linearity and dynamic range with excellent power efficiency. The primary application field for the MAX2685EEE+ is RF mixers for wireless systems, including base stations and remote antennas (RANs). The device can also be used in satellite communications, military communications, and microware radar systems.
Working Principle
The MAX2685EEE+ is a mixer with an input stage and active mixer. The input stage uses differential input architecture to reject common-mode signals. A differential pre-amplifier stage provides gain and adjusts the input signal level. The active mixer combines two radio frequency (RF) signals to create two sums and two differences (intermediate frequency (IF) signals). The IF signals are amplified by a wideband amplifier before being output to the external circuitry.
The active mixer uses a two-stage amplifier to reduce distortion. It also minimizes distortion caused by load-based fluctuation in input impedance at the mixer. The mixer bias is controlled by an external resistor, allowing for configuration of the optimum bias for different application scenarios. The device also includes an integrated voltage regulator, allowing the device to operate over a wide range of supply voltages.
The input-stage differential amplifier is optimized for low-noise operation, and the wideband amplifier is optimized for linearity. This combination gives the MAX2685EEE+ a high third-order intercept point (IP3), with larger-signal performance than competitive parts. The IP3 is easily configured to operate optimally for the specific application. The device also provides excellent dynamic range and linearity, making it suitable for use in wireless radio systems with low-noise signals.
The MAX2685EEE+ is powered by an external positive voltage source, and includes an integrated regulator, eliminating the need for a separate power supply for the device. The device also includes a voltage-controlled oscillator (VCO) that can be used to optimize the frequency response over the entire frequency band. The device is also designed to handle a wide range of input frequencies, with a wide frequency range of 400 MHz to 6 GHz.
The MAX2685EEE+ provides an efficient solution for RF mixers, and is designed for low-noise and high-dynamic-range applications. It also includes a wide range of features, such as an integrated voltage regulator and VCO, allowing it to be easily tailored to almost any RF mixer application. The device is also optimized for high IP3, linearity, and power efficiency, making it an excellent solution for wireless applications.
