Maxim has introduced the MAX2659 high-gain, low-noise amplifier (LNA) for GPS, Galileo and GLONASS applications. Designed using Maxim's advanced, low-power SiGe BiCMOS process, this device achieves a very high 20,5 dB gain and an ultra-low noise figure of 0,8 dB while maximising the input-referred 1 dB compression point and third-order intercept point at
-12 dBm and -2 dBm, respectively. Consequently, said to have the industry's highest gain and lowest noise-figure among SiGe BiCMOS LNAs, the MAX2659 is ideal for a wide range of low-cost consumer applications, including automotive navigation, asset tracking, cellular handsets, portable navigation devices (PNDs), digital cameras, laptops, and ultra-mobile personal computers (UMPCs). The MAX2659 operates from a +1,6 V to +3,3 V single supply and consumes only 4 mA. To further maximise battery life, it reduces the supply current to less than 1 μA in shutdown mode. Available in a tiny, 1,5 mm x 1,0 mm x 0,75 mm, leadless, 6-pin microDFN package, the MAX2659 is fully specified over the -40°C to +85°C temperature range.
