Description

The MAX2359EGI-T is a single-and multi-band LNA/mixer IC optimized for CDMA, GSM, and TDMA applications in cellular and PCS bands. It belongs to the MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/MAX2531/MAX2537/MAX2538 family of ICs. Along with the cellular and PCS signals, it also features a GPS LNA/mixer signal path for E911 and traveler assistance applications. It can route the signals to different IF ports, allowing for flexibility in IF filtering with different bandwidths. The MAX2359EGI-T is designed to eliminate the need for external components, such as external GPS VCO and interstage GPS SAW filter. It operates in triple band and quadruple mode with ultra-low current consumption. The IC comes in a compact 28-pin QFN package.
