MAX2691：L2 Band GPS Low-Noise Amplifier

Low-Noise-Figure GPS LNA in an Ultra-Small WLP; Versions Available with Different Levels of Gain

The MAX2691 low-noise amplifier (LNA) is designed for GPS L2 applications. Designed in Maxim's advanced SiGe process, the device achieves high gain and low noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. The MAX2691 provides a high gain of 17.5dB and sub 1dB noise figure. The device operates from a +1.6V to +3.6V single supply. The optional shutdown feature in the device reduces the typical supply current to 4µA. The device is available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).

Key Features High-Power Gain: 17.5dB Low-Noise Figure: 0.93dB Integrated 50Ω Output Matching Circuit Low Supply Current: 4.3mA Wide Supply Voltage Range: 1.6V to 3.6V Low Bill of Materials: One Inductor, Two Capacitors Small Footprint: 0.86mm x 0.86mm Thin Profile: 0.65mm 0.4mm-Pitch Wafer-Level Package (WLP)
