LEE-9+

Overview

The LEE-9+ is a monolithic microwave integrated circuit (MMIC) linear gain block amplifier manufactured by Mini-Circuits. It operates over a frequency range of 0Hz to 8GHz with a typical gain of 7.7dB. The device features a P1dB output power of 14.1dBm and a third-order intercept point (OIP3) of 19.7dBm. It requires a supply voltage between 3.6V and 4.4V, drawing approximately 50mA of current. The component is housed in a compact 4-SMD, no-lead FG873 package, suitable for surface-mount assembly.

Feature Summary

• Wideband operation from DC to 8GHz
• High linearity with significant OIP3 performance
• Compact 3x3mm surface-mount package design

Applications

• Cellular infrastructure systems
• Personal Communication Services (PCS) applications
• Broadband RF signal conditioning circuits

Procurement Notes

Verify the specific ordering suffix to ensure RoHS compliance and correct packaging configuration. Confirm that the supplier provides official datasheets matching the FG873 package outline. Check for authenticity through authorized distribution channels to avoid counterfeit components. Ensure storage conditions align with the moisture sensitivity level specifications provided in the manufacturer documentation.

Selection Notes

Select this component when a wideband, linear amplification solution is required up to 8GHz. Consider the 50Ω impedance matching for seamless integration into standard RF chains. Evaluate the 50mA current consumption against system power budgets. The flat gain characteristic makes it suitable for applications requiring consistent signal amplification across the entire operational bandwidth without significant frequency-dependent variation.

Part Context

This part belongs to the LEE series of SMT MMIC amplifiers from Mini-Circuits. These devices are designed as linear gain blocks using HBT technology. The series offers various models optimized for different frequency ranges and power levels, all sharing a common compact form factor. The LEE-9+ specifically targets ultra-wideband applications within this lineup.

Replacement Considerations

No direct public substitute part numbers are confirmed in the available documentation. Designers should evaluate other Mini-Circuits LEE series variants or comparable wideband MMICs based on specific gain and linearity requirements if replacement is necessary.
