LEE-19+

Overview

The LEE-19+ is a surface-mount monolithic microwave integrated circuit (MMIC) amplifier manufactured by Mini-Circuits. It operates across a frequency range of 0 Hz to 8 GHz, providing a typical gain of 9 dB. The device requires an operating supply voltage of 3.6 V and draws a current of 40 mA. It is housed in a compact 3x3 mm MCLP plastic package with four terminals. The component is designed for high dynamic range performance and features a predicted mean time between failures (MTBF) of 3,000 years at an ambient temperature of 85°C.

Feature Summary

• Provides broadband amplification from DC to 8 GHz
• Encapsulated in a compact 3x3 mm MCLP plastic package
• Delivers high dynamic range performance
• Ensures reliable operation with extended MTBF ratings

Applications

• Cellular infrastructure systems
• Personal Communication Services (PCS) networks
• RF signal conditioning circuits
• Broadband communication equipment

Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to ensure correct configuration. Confirm that the requested part matches the required electrical specifications and package type. Check RoHS compliance status if environmental regulations apply to your project. Ensure compatibility with standard surface-mount assembly processes given the MCLP form factor.

Selection Notes

Select this component when a wide bandwidth covering DC to 8 GHz is required within a small footprint. The 9 dB gain and 40 mA current draw suit applications needing moderate amplification without excessive power consumption. Consider the 3.6 V supply requirement during system power budgeting. Evaluate thermal management needs based on the 85°C maximum operating temperature specification.

Part Context

The LEE-19+ belongs to the LEE series of surface-mount monolithic amplifiers from Mini-Circuits. This family includes variants such as the LEE-29+, LEE-39+, and others, which share similar packaging but differ in gain and frequency characteristics. These components are designed for integration into RF front-end modules and general-purpose amplification tasks requiring high reliability.

Replacement Considerations

Direct substitutes within the same series include LEE-29+, LEE-39+, LEE-49+, and LEE-59+. Verify that alternative models meet the specific gain and frequency requirements of the design. Cross-reference pinouts and thermal characteristics to ensure mechanical and electrical compatibility during replacement.
