MAX2090ETP+

Overview

The MAX2090ETP+ is a high-linearity analog variable-gain amplifier (VGA) designed for 50Ω systems operating in the 50MHz to 1000MHz frequency range. It integrates a SiGe BiCMOS attenuator, amplifier, error amplifier, and alarm circuit within a compact 20-pin TQFN package. The device offers a gain range of -10.9dB to +26.1dB with a noise figure of 4dB. Key performance metrics include an OIP3 linearity of +38dBm at 100MHz and an output -1dB compression point of +17.5dBm. It operates from a single +5.0V supply with a range of +4.75V to +5.8V and is guaranteed over an extended temperature range of -40°C to +95°C.

Feature Summary

• Integrates analog attenuator, amplifier, error amplifier, and threshold alarm circuit in a single monolithic SiGe BiCMOS structure
• Features wide RF bandwidth coverage from 50MHz to 1000MHz suitable for various receiver and transmitter applications
• Provides high linearity with +38dBm OIP3 and low noise figure of 4dB including attenuator insertion loss
• Includes adjustable threshold alarm circuit and error amplifier for precise level control in AGC loops

Applications

• Cellular infrastructure receiver front-ends
• Instrumentation systems requiring variable gain control
• Radar signal processing chains
• Telecommunications equipment level control

Procurement Notes

Verify the specific suffix 'T' if tape-and-reel packaging is required, as the base part number may denote tube packaging. Confirm RoHS compliance status through official Analog Devices documentation. Ensure the supplier provides valid traceability for the Maxim Integrated brand history under Analog Devices. Check for any regional distribution restrictions or limited availability notices prior to ordering.

Selection Notes

Select this component when a wideband VGA with integrated alarm functionality is needed for 50Ω systems. It is suitable for applications requiring high linearity and low noise across the VHF/UHF spectrum. Consider the 20-pin TQFN package size for space-constrained designs. Ensure the control voltage interface matches the external analog control requirements for the attenuator section.

Part Context

The MAX2090 belongs to the Maxim Integrated family of high-performance RF amplifiers. It is part of a series of variable-gain amplifiers designed for robust signal conditioning in demanding environments. The device leverages SiGe BiCMOS technology to achieve high linearity and low power consumption within a small footprint, supporting both cellular and general instrumentation markets.

Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio that offer similar gain ranges and frequency coverage. Verify if updated revisions of the MAX2090 exist with minor parameter improvements. Ensure any substitute maintains the same TQFN-20 package dimensions and thermal pad requirements for PCB layout compatibility.
