MAX2090ETP+T

Overview

The MAX2090ETP+T is a high-linearity analog variable-gain amplifier (VGA) designed for 50Ω systems operating within the 50MHz to 1000MHz frequency range. It integrates a SiGe BiCMOS attenuator, amplifier, error amplifier, and alarm circuit. The device provides 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 (range +4.75V to +5.8V) and features a compact 20-pin TQFN package (5mm x 5mm). Electrical performance is guaranteed over an extended temperature range of -40°C to +95°C.

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm that the specific suffix matches the required package and temperature grade. Check current availability status as supply conditions may vary. Ensure compatibility with existing design specifications regarding voltage levels and interface requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated VGA functionality with built-in alarm capabilities. Consider the +38dBm OIP3 linearity for high-dynamic-range applications. Evaluate the 4dB noise figure against system sensitivity requirements. Verify that the 50MHz to 1000MHz bandwidth aligns with target signal frequencies. Assess thermal management needs given the extended temperature operation range.
