LNA Boasts 20.5-dBm Gain, 0.8-dBm Noise Figure

Taking advantage of the company’s advanced, low-power SiGe BiCMOS process, the MAX2659 high-gain, low-noise amplifier (LNA) from Maxim Integrated Products achieves a 20.5-dB gain and a noise figure of 0.8 dB. The device hits these performance levels while maximizing the input-referred 1-dB compression point and third-order intercept point at -12 dBm and -2 dBm, respectively. The LNA is suitable for GPS, Galileo, and GLONASS applications in a wide range of low-cost consumer devices.

The MAX2659 operates from a single 1.6- to 3.3-V supply and consumes 4 mA. To further maximize battery life, it reduces the supply current to less than 1 µA in shutdown mode. Available in a 1.5- by 1.0- by 0.75-mm leadless, 6-pin microDFN package, the MAX2659 is fully specified over the -40ºC to 85ºC temperature range. Prices start at $0.70 in quantities of 1000.
