General Description

The MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/MAX2327 high-performance silicon germanium (SiGe) receiver front-end ICs set a new industry standard forlow noise and high linearity at a low supply current. This family integrates a variety of unique features such as an LO frequency doubler and divider, dual low-noise amplifier (LNA) gain settings, and a low-current paging mode that extends the handset standby time.
