BLF8G27LS-100GVQ

Overview

The BLF8G27LS-100GVQ is a 100 W LDMOS power transistor designed for base station applications in the 2500 MHz to 2700 MHz frequency range. It features improved video bandwidth and low memory effects, making it suitable for multi-carrier systems like 3GPP test model 1 with 64 DPCH. The device operates at VDS = 28 V and IDq = 900 mA, delivering 25 W output power with 17 dB gain and 28% drain efficiency. It utilizes an earless flanged ceramic package (SOT1244C) with decoupling leads to enhance thermal stability and performance.

Feature Summary

• Decoupling leads enable improved video bandwidth of 110 MHz typical
• Lower output capacitance improves performance in Doherty applications
• Designed for low memory effects providing excellent pre-distortability
• Internally matched for ease of use

Applications

• RF power amplifiers for base stations
• Multi carrier applications in the 2500 MHz to 2700 MHz frequency range

Procurement Notes

Verify the specific ordering suffix GVQ against official Ampleon documentation to confirm the SOT1244C package variant. Ensure compliance with RoHS Directive 2002/95/EC requirements during procurement. Confirm that the component meets the absolute maximum ratings defined in the product data sheet prior to integration into designs.

Selection Notes

Select this component for broadband operations requiring high efficiency and ruggedness in class-AB operation. Consider the SOT1244C package dimensions and thermal resistance characteristics when designing heat sinks. Verify impedance matching networks using the provided load-pull data for optimal power gain and efficiency across the target frequency band.

Part Context

This part belongs to the BLF8G27LS series of power LDMOS transistors from Ampleon. The 'GV' suffix typically denotes the SOT1244C earless flanged ceramic package variant, distinct from the standard 'V' version which uses the SOT1244B package. Both variants share identical electrical specifications and are intended for similar base station RF amplifier applications.

Replacement Considerations

BLF8G27LS-100V serves as a functional equivalent within the same series but utilizes the SOT1244B package instead of SOT1244C. Designers must verify mechanical fit and pinout compatibility before substitution.
