Features S High-Power Gain: 19d B (MAX2686) S Ultra-Low-Noise Figure: 0.75d B (MAX2686) S Integrated 50Ω Output Matching Circuit S Low Supply Current: 4.1m A S Wide Supply Voltage Range: 1.6V to 3.3V S Low Bill of Materials: One Inductor, Two Capacitors S Small Footprint: 0.86mm x 0.86mm S Thin Profile: 0.65mm S 0.4mm-Pitch Wafer-Level Package (WLP) General Description The MAX2686/MAX2688 low-noise amplifiers (LNAs) are designed for GPS L1, Galileo, and GLONASS applications. Designed in Maxim’s advanced Si Ge process, the devices achieve high gain and ultra-low-noise figure while maximizing the input-referred 1d B pression point and the 3rd-order intercept point. The MAX2686 provides a high gain of 19d B. The MAX2688 supplies 15d B of gain while attaining higher linearity. The devices operate from a +1.6V to +3.3V single supply. The optional shutdown feature in the devices reduces the supply current to less than 10FA. The devices are available in a very small, lead-free, Ro HS-pliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).
