BLM7G1822S-20PBGYZ

Overview

The BLM7G1822S-20PBGYZ is a dual-section, two-stage power MMIC utilizing GEN7 LDMOS technology. It operates in the 1805 MHz to 2170 MHz frequency range with a maximum drain-source voltage of 65 V and a case temperature limit of 150 °C. Typical performance at 2167.5 MHz includes a power gain of 32.3 dB, drain efficiency of 23%, and output power of 2 W under single-carrier W-CDMA conditions. The device features integrated temperature-compensated bias and ESD protection.

Feature Summary

• Dual-section architecture providing high section-to-section isolation for flexible circuit topologies
• Integrated temperature compensated bias and externally accessible stage biasing
• On-chip matching designed for ease of use in broadband applications
• Built-in ESD protection compliant with C1 and HBM 1A classifications

Applications

• RF power MMIC for multi-carrier base stations supporting GSM, W-CDMA, and LTE standards
• General purpose driver or small cell final amplifier stages
• Doherty, quadrature combined, push-pull, and dual section circuit topologies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm lead frame material and plating specifications. Confirm package variant availability as the datasheet distinguishes between flat (SOT1211-3) and gull wing (SOT1212-3) outlines. Ensure component handling procedures strictly adhere to ESD sensitivity guidelines during assembly.

Selection Notes

Select this component for broadband applications requiring operation between 1805 MHz and 2170 MHz. Evaluate thermal resistance requirements based on the junction-to-case values provided for driver and final stages. Consider the ruggedness capabilities regarding load mismatch tolerance when designing for class-AB operation environments.

Part Context

This part belongs to the BLM7G1822S series of LDMOS power MMICs from Ampleon. The series utilizes advanced GEN7 technology to deliver high power gain and efficiency. Variants within the series typically differ by package outline style and manufacturing revision, serving as key components in modern wireless infrastructure amplifiers.

Replacement Considerations

Direct replacements include the BLM7G1822S-20PB and BLM7G1822S-20PBG. Verify that the substitute matches the required package type, specifically SOT1211-3 for flat leads or SOT1212-3 for gull wing leads, to ensure mechanical compatibility.
