VMMK-1218-TR1G

Overview

The VMMK-1218-TR1G is a low noise amplifier manufactured by Broadcom Limited, designed for wideband RF applications. It operates across a frequency range of 0.5 GHz to 18 GHz using E-PHEMT technology. The component is housed in a wafer-scale package, facilitating integration into compact systems. Key electrical specifications include a gain of approximately 16 dB and a noise figure of 1.7 dB at 3 GHz. It requires a 3V supply voltage and draws 37mA of current. The device is rated for surface mount installation and is packaged in tape and reel format for automated assembly.

Feature Summary

• Ultra-wideband operation spanning from 0.5 GHz to 18 GHz
• Low noise figure performance suitable for sensitive receiver front-ends
• Wafer-scale packaging for minimal footprint and high reliability

Applications

• GPS and GNSS receiver front-ends
• Wideband test and measurement equipment
• Electronic warfare and signal intelligence systems

Procurement Notes

Verify the specific ordering suffix and revision level against the latest manufacturer datasheet before procurement. Confirm that the wafer-scale package handling requirements align with your manufacturing capabilities. Check for end-of-life status or alternative recommendations from Broadcom if long-term supply stability is required for production.

Selection Notes

Select this component when a single-stage amplifier must cover an extremely broad frequency spectrum without retuning. Ensure the system can accommodate the wafer-scale package form factor. Verify that the 3V supply voltage and 37mA current consumption fit within the power budget of the target application.

Part Context

This part belongs to the VMMK series of monolithic microwave integrated circuits from Broadcom. It utilizes E-PHEMT technology to achieve high performance in a small form factor. The TR1G suffix typically indicates tape and reel packaging with lead-free compliance, distinguishing it from bulk or sample packages.

Replacement Considerations

Consult Broadcom's official compatibility guides for direct replacements. Generic equivalents may not match the 0.5-18 GHz bandwidth or the specific noise figure characteristics. Verify pinout and thermal requirements if substituting with other wideband LNA technologies.
