MAX19793ETX+

Overview

The MAX19793ETX+ is a dual, general-purpose analog voltage variable gain attenuator (VVA) designed for 50Ω systems. It operates within a frequency range of 500 MHz to 4 GHz. The device provides an attenuation range of 0 dB to 46.4 dB per channel. It utilizes Silicon Germanium (SiGe) technology and is housed in a 36-TQFN package with exposed pad.

Feature Summary

• Dual-channel architecture providing independent control for each path
• Analog voltage-controlled operation for precise attenuation adjustment
• Broadband performance covering 500 MHz to 4 GHz frequency spectrum

Applications

• RF signal conditioning in wireless infrastructure
• Test and measurement equipment requiring variable attenuation
• Phased array antenna systems

Procurement Notes

Verify the specific suffix 'ETX+' against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure the operating temperature range of -40°C to +100°C aligns with system requirements. Confirm RoHS compliance status as indicated in current manufacturer specifications before finalizing procurement orders.

Selection Notes

Select this component when dual independent variable attenuation is required in the 500 MHz to 4 GHz band. Consider the SiGe technology for performance characteristics. Evaluate the 36-TQFN package constraints for PCB layout and thermal management needs compared to alternative surface-mount options.
