Digi-Key – High-gain LNA designed for GPS, Galileo, and GLONASS applications (MAX2659)Aug 2 2012 - Semiconductors [More Semiconductors Articles]
Now available from Digi-Key, Maxim’s 0.8dB noise figure, 20dB gain, GPS low-noise amplifier (LNA) offers improved performance over existing solutions, says the company.
The MAX2659 high-gain LNA is designed for GPS, Galileo, and GLONASS applications. Designed in Maxim’s advanced SiGe process, the device achieves a 20.5dB gain and an ultra-low noise figure of 0.8dB while maximizing the input-referred 1dB compression point and the 3rd-order intercept point at -12dBm and -5dBm, respectively.
The MAX2659 operates from a 1.6 to 3.3V single supply and consumes only 4.1mA. The shutdown feature in the device reduces the supply current to be less than 1 µA. The MAX2659 is available in a very small, lead-free, RoHS-compliant, 1.5mm x 1mm x 0.75mm, 6-pin µDFN package.
Also available, the MAX2659 evaluation kit (EV kit) simplifies evaluation of the MAX2659 GPS/GNSS low-noise amplifier (LNA). The EV kit enables testing of the device’s performance and requires no additional support circuitry. The MAX2659 EV kit is fully assembled with the MAX2659 IC on-board and incorporates input matching components to optimize performance. The EV kit’s signal inputs and outputs use SMA connectors to facilitate the connection of RF test equipment.
Applications include automotive navigation, avionics, cellular phones with GPS, location-enabled mobile devices, notebook / ultra-mobile PCs, personal navigation devices (PNDs), recreational / marine navigation and telematics (asset tracking and management).More news from Digikey
