The BGU7003 is a wideband Silicon Germanium Amplifier MMIC for high speed, low noise applications. It can be used mainly for LNA applications up to 6 GHz like GPS, satellite radio, cordless phone. The BGU7003 contains one RF stage and internal bias that is temperature stabilized. It also contains a power down function to shutdown the amplifier by means of a logic signal on the enable pin.

The BGU7003 is ideal for use in portable electronic devices, such as mobile phones, Personal Digital Assistants (PDAs), Personal Navigation Devices (PNDs) etc.

The GPS LNA EValuation Board (EVB) is designed to evaluate the performance of the BGU7003 applied as a GPS LNA. In this document, the application diagram, board layout, bill of material, and some typical results are given.
