MAX19790ETX+T

Attenuators Overview

The MAX19790ETX+T is a dual analog voltage-controlled RF attenuator from Analog Devices. It operates within a frequency range of 250 MHz to 4 GHz with a nominal impedance of 50 Ohms. The device provides an attenuation range of 22 dB to 44 dB and supports a power rating of 2.1 W. Packaged in a 36-WQFN exposed pad, it is designed for high-linearity signal control in wireless infrastructure.

Attenuators Feature Summary

• Dual-channel architecture enabling independent or simultaneous attenuation control
• Analog voltage-controlled operation for precise signal level management
• High power handling capability suitable for demanding RF environments

Attenuators Applications

• Base station transmit/receive path signal conditioning
• Wireless infrastructure linearization circuits
• Test and measurement equipment requiring variable attenuation

Attenuators Procurement Notes

Verify the specific suffix ETX+T against official datasheets to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 36-WQFN exposed pad. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Attenuators Selection Notes

Select this component when dual-channel attenuation is required across the 250 MHz to 4 GHz spectrum. Consider the 2.1 W power rating and 50 Ohm impedance match for system integration. Evaluate thermal performance requirements due to the exposed pad design for adequate heat dissipation in high-power applications.
