Product Overview
The BLF7G24LS-140,118 is a 140W high-power LDMOS RF transistor manufactured by Ampleon (formerly NXP). Designed for 2300MHz–2400MHz wireless base stations, it operates at 28V drain voltage based on 7th-gen LDMOS technology. It delivers high gain, excellent efficiency and linearity for multi-carrier signals. Housed in SOT502B flangeless ceramic air-cavity package, it withstands VSWR 10:1 load mismatch, ideal for macro cells, micro base stations and Doherty amplifiers.
Core Advantages
140W Peak Output Power at 2.3GHz – 2.4GHz Band
Provides continuous and peak power output up to 140W @28V, supporting reliable signal amplification for 2.3GHz LTE network equipment.
7th Generation LDMOS Technology
Optimized for high PAE, low memory effect and stable linearity for high PAPR digital modulation standards including LTE and W-CDMA.
Internal Input Impedance Matching
Built-in input matching simplifies 50-ohm circuit design and reduces peripheral components. External output matching circuit is required.
Flangeless Ceramic Air-Cavity Package & Ruggedness
SOT502B packaging ensures low thermal resistance and can sustain severe mismatch conditions up to VSWR 10:1 without device damage.

Frequently Asked Questions
Q1: What does the “,118” suffix represent in BLF7G24LS-140,118?
A: The “,118” suffix is the commercial packaging code designating standard Tape & Reel delivery format for ceramic components.
Q2: What is the primary difference between BLF7G24LS-140 and BLF7G24LS-100?
A: The BLF7G24LS-140 delivers higher peak output power (140W vs 100W) at 28V. Normally used as peak amplifier, while BLF7G24LS-100 works as main amplifier in symmetrical Doherty circuit.
Q3: Does the BLF7G24LS-140,118 feature integrated impedance matching?
A: Only internal input matching is integrated. External output matching network must be designed separately.
Q4: How should the ceramic SOT502B package be installed for optimal heat dissipation?
A: Mount the base flat and secure directly onto precision-machined heatsink with mounting screws and thermal interface material (TIM) to minimise thermal resistance.
Q5: Are there alternative replacement models for BLF7G24LS-140,118?
A: BLF7G24LS-140,112 is electrically identical, only packaging format differs (Tube/Tray). Verify mechanical package outline before replacement.
Q6: What operating frequency band is BLF7G24LS-140,118 optimized for?
A: It is designed for 2300MHz ~ 2400MHz, targeted at 2.3GHz LTE wireless communication base station infrastructure.
Q7: What maximum load mismatch can this LDMOS transistor withstand?
A: The device can sustain severe load mismatch conditions up to VSWR 10:1 without permanent device degradation.
