LEE-29+

Overview

The LEE-29+ is a wideband gain block amplifier manufactured by Mini-Circuits, designed for high dynamic range performance. It operates from 0 Hz to 8 GHz and utilizes InGaP technology. The device provides a typical gain of 10.6 dB with a noise figure of 5.5 dB. Key linearity metrics include a P1dB compression point of 11.5 dBm and an OIP3 of 25.5 dBm. It functions on a 3.6 V supply with a current draw of 40 mA. The component is housed in a compact MCLP-4 surface mount package.

Feature Summary

• Wideband operation covering DC to 8 GHz
• High dynamic range with repeatable lot-to-lot performance
• InGaP technology for robust signal amplification

Applications

• Cellular PCS systems
• Radar system frontends
• Communication test equipment
• Broadband amplification applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compliance with RoHS standards and correct packaging specifications. Confirm that the requested variant matches the required frequency range and power characteristics. Cross-reference the datasheet parameters with your system requirements before finalizing the purchase order to avoid compatibility issues.

Selection Notes

Select this component when a wideband solution up to 8 GHz is required with moderate output power capabilities. The 11.5 dBm P1dB rating makes it suitable for intermediate gain stages rather than final power amplification. Consider the MCLP-4 package size for space-constrained PCB layouts. Ensure the 3.6 V supply voltage aligns with the system's power architecture.

Part Context

This part belongs to the LEE series of monolithic amplifiers from Mini-Circuits. It is distinct from the GALI-29+, which offers higher gain but operates up to 7 GHz. The LEE-29+ focuses on wideband coverage and high dynamic range within a small form factor. It serves as a versatile active component for RF signal conditioning in modern communication infrastructure.

Replacement Considerations

The GALI-29+ is a related model offering higher gain (12.9 dB) but with a lower maximum frequency of 7 GHz. Direct substitution requires verifying if the increased gain and reduced bandwidth meet the specific circuit design constraints. No other direct substitutes are confirmed in public documentation.
