NXP Semiconductors BLF8G10LS-270V,112

Overview

BLF8G10LS-270V,112 from NXP Semiconductors is a 270 W LDMOS RF power transistor optimized for base station amplifiers operating from 790 MHz to 960 MHz. It delivers 19.5 dB power gain, 31 % drain efficiency, and −37 dBc adjacent channel power ratio (ACPR) at 67 W output under 2-carrier W-CDMA conditions (PAR = 8.4 dB), with rugged VSWR = 10:1 load mismatch tolerance at 820–960 MHz.

For engineers reviewing the BLF8G10LS-270V,112 datasheet, BLF8G10LS-270V,112 pinout, BLF8G10LS-270V,112 application, or BLF8G10LS-270V,112 equivalent, this page provides verified circuit role (RF power amplification in W-CDMA macro base stations), thermal resistance (0.257 K/W), video bandwidth (55 MHz typical), decoupling lead configuration, and validated alternatives for broadband cellular infrastructure design.

Technical Context

The BLF8G10LS-270V,112 operates as a common-source class-AB RF power amplifier with internally matched input/output impedances across 790–960 MHz. Its low R_th(j-c) = 0.257 K/W enables stable thermal performance at high case temperatures, while integrated ESD protection and dual decoupling leads support robust operation in Doherty architectures.

Designed specifically for multi-carrier W-CDMA signals, it achieves low memory effects and pre-distortability via reduced output capacitance and optimized gate layout. The device sustains full 270 W rated output under VSWR = 10:1 mismatch at key band edges (820/869/920/960 MHz) with V_DS = 28 V and I_Dq = 2000 mA.

FAQ

What is the maximum continuous drain current rating for BLF8G10LS-270V,112?

The BLF8G10LS-270V,112 has no explicit maximum continuous drain current rating in its datasheet. Instead, it specifies a drain leakage current (I_DSS) ≤ 4.2 µA at V_DS = 28 V and V_GS = 0 V, and a drain cut-off current (I_DSX) of 82 A typical at V_GS = V_GS(th) + 3.75 V and V_DS = 10 V. Operation is defined by limiting values including V_DS ≤ 65 V and T_j ≤ 225 °C, with thermal design governed by R_th(j-c) = 0.257 K/W.

Does BLF8G10LS-270V,112 support 5G NR sub-1 GHz operation?

The BLF8G10LS-270V,112 is characterized and guaranteed for 790–960 MHz operation per its datasheet, covering LTE Bands 5/8/20 and W-CDMA. While some 5G NR deployments use overlapping spectrum (e.g., n5, n8), NXP does not specify or validate BLF8G10LS-270V,112 for 5G NR modulation schemes, OFDM symbol structure, or associated ACLR requirements. Use in 5G requires full system-level validation.

What is the recommended gate bias voltage for BLF8G10LS-270V,112 in class-AB operation?

The BLF8G10LS-270V,112 is specified for class-AB operation with I_Dq = 2000 mA at V_DS = 28 V. Its gate-source threshold voltage (V_GS(th)) is 1.5–2.3 V, and typical gate bias is set to achieve the specified quiescent current. The datasheet does not prescribe a fixed V_GS value; instead, bias networks must be tuned to maintain I_Dq = 2000 mA across temperature and unit variation, using the provided DC characteristics table and thermal derating guidance.

Can BLF8G10LS-270V,112 be used in pulsed RF applications?

Yes - the BLF8G10LS-270V,112 datasheet includes graphical data for CW pulsed operation (Section 7.5.2 and 7.5.6), confirming validated performance under pulsed conditions. Key parameters like power gain and drain efficiency are plotted for pulsed waveforms at 869/881.5/894 MHz. Thermal limits and ruggedness ratings apply equally, but pulse duty cycle and repetition rate must stay within safe operating area boundaries defined by peak junction temperature and average power dissipation.

Is BLF8G10LS-270V,112 RoHS compliant and lead-free?

Yes - the BLF8G10LS-270V,112 complies with Directive 2002/95/EC (RoHS) and is lead-free. This is explicitly stated in Section 1.2 ("Features and benefits") of the datasheet, and the SOT1244B package construction uses lead-free terminations and ceramic materials consistent with RoHS requirements. No exemptions are cited, and the part meets full substance restrictions for Cd, Pb, Hg, Cr(VI), PBB, and PBDE.
