Tiny Low-Noise Amplifiers for HSPA/LTE

Innovative LNAs Provide Leading Broadband Operation and Built-In Features that Ensure Optimized Performance

Please check latest availability status for a specific part variant.


The MAX2666/MAX2668 are a family of low-noise amplifiers (LNAs) intended for use in HSPA mobile handsets. The LNAs provide three programmable gain states, delivering superior optimization for linearity and sensitivity versus traditional two-gain-state LNAs.

The MAX2666 is optimized for use over the 2100MHz to 2200MHz frequency range (bands 1, 4, and 10) and offers a typical maximum gain of 14.5dB.

The MAX2668 is optimized for use over the 850MHz to 1000MHz frequency range (bands 5, 6, and 8) and provides a typical maximum gain of 17dB.

Each device is available in a tiny 1mm x 1.5mm, 6-pin ultra-thin LGA package.
