EVALUATION KIT AVAILABLE MAX2674/MAX2676 GPS/GNSS LNAs with Antenna Switch and Bias General Description Features S Eliminate Discrete Antenna Sensing, Switching, The MAX2674/MAX2676 are ultra-small, high-IP3, low- and Bias Networks noise amplifiers (LNAs) designed for GPS L1, Galileo, Autodetect Antenna Connection and GLONASS applications. Designed in Maxims Provide Antenna Bias advanced SiGe process, the devices are also equipped Short-Circuit Protection with an autosensing feature for applications that enable the use of external antennas. These high-performance S Wide 1.6V to 3.6V Supply Voltage Range LNAs provide high gain and an ultra-low noise figure S Ultra-Small Footprint (0.86mm x 1.26mm) WLP while optimizing the input-referred 2dB compression Package point and 3rd-order intercept point. S For Applications Without Antenna Port, Use Pin- The ultra-small size is ideal for front-end modules and Compatible 4-Bump MAX2686/MAX2687/MAX2688 receiver applications in cellular phones, smartphones, LNA PDAs, PNDs, or other custom GNSS applications. The MAX2674/MAX2676 operate from a 1.6V to 3.6V single Applications supply. The MAX2674 is optimized for high gain, while Front-End SAW Modules the MAX2676 is optimized for high linearity. A shutdown Receiver Modules feature is present in both devices reducing the supply Cellular and Smartphones current to less than 10FA. The antenna port automati- Telematics (Asset Tracking and Management) cally senses when an external antenna is connected, Personal Navigation Devices (PNDs) eliminating the need for additional control circuitry Recreational, Marine Navigation while also providing improved short-circuit protection. The MAX2674/MAX2676 are available in an ultra-small, RoHS-compliant 0.86mm x 1.26mm x 0.64mm wafer- Ordering Information level package (WLP).
