MAX2091ETP+

Overview

The MAX2091ETP+ is a monolithic up-converting mixer integrated circuit manufactured by Analog Devices Inc. utilizing SiGe BiCMOS technology. It operates with an intermediate frequency (IF) range of 50MHz to 500MHz and produces an RF output between 1735MHz and 1935MHz. The device features a variable gain amplifier, mixer stage, and image filter within a single package. Key electrical specifications include an output third-order intercept point (OIP3) of +24.5dBm, an output 1-dB compression point of +12dBm, and a noise figure of 5.4dB. The IF attenuator control range spans 37dB with a maximum gain of 23dB. The component is housed in a 20-TQFN (5x5 mm) package.

• Provides high linearity performance with specified OIP3 and P1dB metrics for signal integrity
• Features adjustable threshold alarm circuitry for real-time signal status monitoring
• Supports external analog control voltage for flexible attenuation management

Applications

• Microwave point-to-point transmitter systems
• Intermediate frequency variable gain stages
• Temperature compensation circuits
• Fixed broadband wireless access networks
• Wireless local loop infrastructure

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity against the manufacturer's current documentation before purchase. Confirm that the RoHS compliance status matches project requirements. Ensure the 20-TQFN footprint dimensions align with the PCB layout design. Check for any regional distribution restrictions or supply limitations that may affect availability. Validate that the operating temperature range meets the environmental conditions of the intended application.

Selection Notes

Select this component when a compact solution combining VGA, mixing, and filtering is required for microwave frequencies. Consider the 5.4dB noise figure and +24.5dBm OIP3 for applications demanding high signal fidelity. The 37dB attenuation range allows for significant dynamic adjustment of the IF signal level. Ensure the system can provide the necessary analog control voltages for the internal attenuator. Verify that the LO and IF frequency ranges fall within the specified 50MHz-500MHz and 1735MHz-1935MHz boundaries respectively.
