MAX19792ETX+

Overview

The MAX19792ETX+ is a dual, general-purpose analog voltage variable attenuator (VVA) designed for 50-ohm systems. It operates within a frequency range of 500 MHz to 4000 MHz. The device features a patented control circuit providing a total attenuation range of 46.4 dB with 10-bit resolution. Key electrical specifications include an insertion loss of 5.3 dB and a power rating of 20 dBm. It requires a 3.3 V supply voltage and functions within an operating temperature range of -40°C to +100°C.

Feature Summary

• Dual-channel architecture for independent signal attenuation control
• Patented control circuitry ensures precise analog voltage adjustment
• High dynamic range with 10-bit resolution across the operational bandwidth

Applications

• Wireless infrastructure base station transceivers
• Test and measurement equipment requiring variable gain control
• Radar systems needing precise signal level management

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status as per current manufacturing data sheets. Check for obsolescence notices or end-of-life announcements prior to finalizing procurement plans. Ensure packaging type matches design requirements for surface mount assembly processes.

Selection Notes

Select this component when dual-channel variable attenuation is required in the 500 MHz to 4 GHz range. Consider the 5.3 dB insertion loss impact on system noise figure. Verify that the 3.3 V supply voltage aligns with existing board power rails. Evaluate thermal performance capabilities given the +100°C maximum operating temperature limit.

Part Context

This part belongs to the Maxim Integrated RF attenuator family, now under Analog Devices. It serves as a critical passive-active hybrid component for managing signal levels in high-frequency communication systems. The TQFN-36 package facilitates compact PCB layout integration for modern wireless applications.
