Blf861a Amplifier Module
Overview
Product sourcing insights & recommendations
I have synthesized the technical specifications and market trends for the BLF861A amplifier module.
The BLF861A is a legacy 150W/300W UHF LDMOS transistor primarily used in broadcast television and high-power radio transmitters. My research indicates that this component is now in its obsolete/legacy phase, with the market shifting toward more efficient GaN (Gallium Nitride) technologies and newer LDMOS generations like the BLF888A.
Current sourcing is limited to "New Old Stock" (NOS) and refurbished pallet modules, with prices ranging from $92 to $239 per unit. For new designs, it is highly recommended to transition to modern equivalents to ensure long-term availability and improved power efficiency.
The comprehensive report below covers detailed specifications, sourcing landscapes, and technology replacement strategies.
