LEE-59+

Overview

The LEE-59+ is a medium power, linear HBT MMIC amplifier from Mini-Circuits, operating from DC to 5000 MHz. It provides a typical gain of 7.6 dB with a noise figure of 4.5 dB. The device requires a 4.8 V supply and draws 65 mA. Key performance metrics include a P1dB compression point of 13.8 dBm and an OIP3 of 16.3 dBm. It is housed in a compact 3x3 mm QFN package.

Feature Summary

• Low phase noise architecture suitable for sensitive RF applications
• Wideband operation covering DC to 5 GHz frequencies
• Linear HBT technology ensuring repeatable lot-to-lot performance

Applications

• S-band upconverter signal chains
• Cellular PCS infrastructure amplification
• General purpose RF signal conditioning

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Mini-Circuits or authorized distributors before procurement. Ensure that the 3x3 mm QFN footprint matches the target PCB design constraints. Confirm that the 4.8 V supply voltage aligns with the system power budget and thermal management capabilities.

Selection Notes

Select the LEE-59+ when a wideband DC-5 GHz solution with low phase noise is required. It is appropriate for designs needing moderate output power (13.8 dBm P1dB) and linearity (16.3 dBm OIP3). Consider the SMT QFN package for space-constrained layouts requiring high repeatability.

Part Context

This component belongs to Mini-Circuits' LEE series of linear HBT amplifiers. These devices are designed for applications demanding high linearity and low noise across broad bandwidths. The LEE-59+ specifically targets S-band and cellular frequency ranges within this product family.
