AMMP-6650-TR1G

Overview

The AMMP-6650-TR1G is a monolithic microwave integrated circuit (MMIC) variable attenuator manufactured by Broadcom Limited. It operates within a frequency range of 0 Hz to 30 GHz and provides an attenuation range from 0.9 dB to 35.6 dB. The device features a 50 Ohm impedance and is housed in an 8-SMD, no-lead package. It requires a maximum supply voltage of 5 V and is designed for surface-mount installation.

Feature Summary

• Provides wideband variable attenuation across the DC to 30 GHz spectrum
• Offers precise attenuation control with a range spanning 0.9 dB to 35.6 dB
• Utilizes a compact 8-SMD leadless package for efficient surface-mount integration

Applications

• RF signal path conditioning in high-frequency communication systems
• Test and measurement equipment requiring precise signal level adjustment
• Phased array radar systems needing dynamic gain control

Procurement Notes

This component has been officially declared obsolete by Broadcom Limited as of July 21, 2016. Verification of current availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Buyers must confirm lot dates and authenticity due to the end-of-life status. Supply chain planning should account for potential scarcity and longer lead times associated with discontinued inventory.

Selection Notes

Engineers selecting this part must consider its specific 0.9 dB to 35.6 dB attenuation range and 30 GHz upper frequency limit. The 50 Ohm impedance matches standard RF infrastructure. Due to the obsolescence notification, alternative components with similar bandwidth and attenuation characteristics should be evaluated for new designs. Package compatibility remains critical for existing PCB layouts utilizing the 8-SMD form factor.

Part Context

The AMMP-6650 series belongs to Broadcom's portfolio of RF attenuators designed for wireless and microwave applications. This specific variant integrates control circuitry into a small footprint, enabling compact system designs. It complements other broadband MMICs in the lineup, offering reliable performance for signal management tasks in demanding RF environments where size and weight are constrained.
