UPG2118K-E3-A

Overview

The UPG2118K-E3-A is an obsolete RF amplifier integrated circuit manufactured by CEL. It is housed in a 20-QFN (4.2x4.2 mm) package and operates within a supply voltage range of 2.8 V to 5.5 V. The device dissipates up to 4 W of power and draws an operating supply current of 30 mA. Classified as an MMIC amplifier, it features one channel and utilizes a VFQFN-20 encapsulation style for signal amplification applications.

Feature Summary

• Provides robust RF signal amplification capabilities
• Utilizes advanced technology for premium performance
• Designed with a compact 20-pin QFN form factor

Applications

• RF signal processing systems
• Integrated circuit development tools
• High-frequency amplifier modules

Procurement Notes

This component is officially listed as obsolete and end-of-life by the manufacturer. Availability is limited to existing stock from third-party distributors rather than direct production runs. Buyers should verify the authenticity and condition of available inventory carefully, as new original units may carry warranty periods but are not actively manufactured. Cross-reference part numbers and datasheets before finalizing any acquisition decisions.

Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. While the 2.8 V to 5.5 V operating range and 30 mA current draw suit specific low-power RF needs, the lack of future supply necessitates careful lifecycle management. Alternative solutions should be evaluated if long-term production stability is required, as this specific variant is no longer supported by active manufacturing lines.

Part Context

The UPG2118K-E3-A belongs to the CEL RF amplifier family, specifically designed for microwave and radio frequency applications. It serves as a monolithic microwave integrated circuit (MMIC) amplifier. The component is distinct from other CEL parts like the UPG2181T5R-E2-A due to its specific 20-QFN packaging and dedicated amplification function rather than switching roles.

Replacement Considerations

No public confirmed substitute part numbers are documented for this obsolete component. Users requiring similar specifications should consult general RF amplifier catalogs or contact the manufacturer directly for legacy support options.
