MAAD-011035-TR0500

Overview

The MAAD-011035-TR0500 is a wideband 5-bit digital attenuator utilizing GaAs pHEMT MMIC technology. It provides an attenuation range of 0 to 31 dB with 1 dB resolution steps across a frequency span of 100 MHz to 30 GHz. The device operates at 50 Ohms and supports serial or parallel control interfaces. Packaged in a lead-free 4 mm x 4 mm 24-lead PQFN with an exposed pad, it functions within a temperature range of -55°C to +85°C.

Procurement Notes

Verify the specific suffix TR0500 against official MACOM documentation to confirm reel quantity and tape specifications. Ensure compatibility with standard SMD reflow profiles for the 24-lead PQFN package. Confirm RoHS compliance status through current datasheets before integration into production environments.

Selection Notes

Select this component when high-frequency broadband attenuation is required with precise digital control. The 5-bit resolution offers sufficient granularity for many RF applications while maintaining low insertion loss characteristics typical of GaAs pHEMT technology. Consider the exposed pad design for thermal management during selection.

Part Context

This part belongs to MACOM's MAAD series of monolithic microwave integrated circuit (MMIC) digital attenuators. These devices are designed for high-reliability applications requiring variable attenuation control in RF signal paths. The series utilizes advanced GaAs processes to achieve performance across multi-octave bandwidths.

Replacement Considerations

Consult MACOM official substitution guides for direct replacements. Verify pinout compatibility and electrical parameter equivalence for any alternative components. Cross-reference package dimensions to ensure mechanical fit within existing PCB layouts.
