Description

M/A-COM’s MAALSS0049 is a GaAs MMIC low

noise amplifier in a lead-free 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 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.
