The MAX2666/MAX2668 are a family of low-noise amplifiers intended for use in HSPA mobile handsets. They 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.
The MAX2666 and MAX2668 are tiny 1 mm × 1.5 mm, 6‑pin ultra‑thin LGA low‑noise amplifiers designed for HSPA/LTE mobile handsets. They provide three programmable gain states and low noise figures for high‑linearity front‑end modules.
Key sections cover absolute maximum ratings, DC and AC electrical characteristics, typical operating curves, pin descriptions, package information, and recommended matching networks for optimal gain, noise figure, and IIP3 performance.
