It employs a monolithic 2-stage design featuring a convenient 50-ohm input/output impedance that minimizes the number of external components required. RF IN GND Pin Configuration The MAALSS0049 is optimized for the GPS frequency of 1.575 GHz. It operates with a single 3 volt to 5 volt supply and has an off chip resistor that can be used to improve the linearity performance. The MAALSS0049 is fabricated using M/A-COM’s E/D process to realize low noise and high dynamic range. The process features full passivation for increased performance and reliability.
