LNA circuit for GPS receivers based on BFP640

Published on Jul 16 2010 // GPS Receiver Circuits

Based on the GPS receiver LNA circuit BFP640



Figure shows the LNA circuit, ie Low Noise Amplifier circuit for a GPS receiver. This is one important part of a GPS receiver. The IC which is used for this purpose is BFP640. It can be used for 1575 MHz Global Positioning Satellite (GPS) Applications. It is conditionally stable from 5MHz to 6 GHz.

This circuit reduces the noise signals and amplifies the signal perfectly.
