MAX2674

The MAX2674/MAX2676 are ultra-small, high-IP3, low-noise amplifiers (LNAs) designed for GPS L1, Galileo, and GLONASS applications. Designed in Maxim's advanced SiGe process, the devices are also equipped with an autosensing feature for applications that enable the use of external antennas. These high-performance LNAs provide high gain and an ultra-low noise figure while optimizing the input-referred 2dB compression point and 3rd-order intercept point.

The ultra-small size is ideal for front-end modules and receiver applications in cellular phones, smartphones, PDAs, PNDs, or other custom GNSS applications. The MAX2674/MAX2676 operate from a 1.6V to 3.6V single supply. The MAX2674 is optimized for high gain, while the MAX2676 is optimized for high linearity. A shutdown feature is present in both devices reducing the supply current to less than 10µA. The antenna port automatically senses when an external antenna is connected, eliminating the need for additional control circuitry 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-level package (WLP).
