MAAD-011048-TR0500

Overview

The MAAD-011048-TR0500 is a wide-band, 5-bit MMIC digital attenuator offering a 31 dB attenuation range with a 1 dB LSB step. It operates from DC to 55 GHz in a 50 Ohm system. The device integrates a CMOS-compatible driver and supports 1.8V CMOS logic interfaces via Parallel or Serial control modes. Packaged in a lead-free 3 mm, 20-lead surface mount laminate package, it provides high-frequency signal attenuation for RF applications.

Feature Summary

• Integrates CMOS-compatible driver for direct interface with 1.8V CMOS logic
• Supports both Parallel and Serial control modes for flexible system integration
• Provides precise 1 dB LSB step resolution across a 31 dB total attenuation range

Applications

• RF test and measurement equipment requiring wideband attenuation
• Wireless communication systems operating at millimeter-wave frequencies
• Phased array radar systems needing variable signal control

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration, as variations exist between reel, cut tape, and MouseReel options. Confirm moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the 20-VFQFN exposed pad footprint aligns with your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this component when a wide bandwidth extending to 55 GHz is required alongside precise digital control. The integrated driver simplifies interface design by eliminating external buffer circuits. Consider the 20-lead laminate package size constraints and thermal management needs associated with high-frequency MMIC operation in dense layouts.

Part Context

This part belongs to MACOM's MAAD series of digital attenuators, designed for high-performance RF and microwave applications. The series typically offers various bit resolutions and frequency ranges to suit different system requirements. The MAAD-011048 specifically targets ultra-wideband scenarios where standard attenuators may lack sufficient frequency coverage.
