2.5 GHz power amplifier for Bluetooth and cordless phones
The Maxim Integrated MAX2246EBL is a 2.5 GHz power amplifier designed for Bluetooth and cordless phone applications. It is supplied in a 9-WFBGA / CSPBGA package (supplier device package 9-UCSP, 1.52x1.52 mm) for surface-mount assembly.
Package and footprint – 9-UCSP (1.52x1.52 mm)
The 9-UCSP package measures 1.52x1.52 mm, a very small footprint suited for space-constrained RF modules. Surface-mount assembly is standard, but the fine-pitch BGA requires careful solder-paste stencil design and X-ray inspection for voiding. The small size means decoupling capacitor placement must be tight to the supply balls to keep RF loop inductance low.
RoHS status – non-compliant
The MAX2246EBL is marked RoHS non-compliant. This means it contains lead or other restricted substances above the RoHS exemption thresholds. For designs destined for EU, UK, or other RoHS-regulated markets, this part cannot be used without an exemption (e.g., for high-reliability or RF performance where no RoHS-compliant alternative exists). Check with your compliance team whether a waiver applies to your product category.
