3. TECHNICAL BRIEF
Fig3.8. The Schematic of GPS RF path circuit of P970
Figure shows the schematic of GPS RF path circuit of P970, The CN801has connected GPS antenna, GPS signal is
routed from connector (CN801) and antenna, through a dielectric band pass filter (FL801) and then is amplified
by The GPS LNA module(U802).
The GPS LNA module combines low noise amplifier with filter. The LNA module has RF character, that is 18.2dB
gain and 0.95dB noise figure and rejected spurious signal.
