| GPS Low Noise Amplifier 1.5 - 1.7 GHz Features * * * * * * High Gain: 20 dB Low Noise Figure: 1.5 dB Good 50 Input / Output Match Single +3 V to +5 V Bias Adjustable Current Low Cost Plastic SOT-26 Package MAALSS0027 V1 Functional Schematic VDD 1 VDD 2 Description M/A-COM's MAALSS0027 is a GaAs MMIC low noise amplifier in a low-cost SOT-26 surface mount plastic package. It employs a monolithic 2-stage design featuring a convenient 50-ohm input/output impedance that minimizes the number of external components required. The MAALSS0027 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 MAALSS0027 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.
