Hi !!
I´m trying to build a gps repeater
with mga8657 rf amplifier.
I´m using the layout
provided in its datasheet and so far there is no
way to receive gps signal on a ET332 gps module
from inside a building.
Circuit details:
(I´m not using the input inductance to improve NF,
just the 50ohm stripline)
DC blocking capacitors:
33pF
Vd bypass capacitor: 220pF
R1: 100ohm
Vd: 7V
At the output there is a patch antenna
of 45 x 46 mm and it is feeded at a point where
it has 50ohm approx.
If someone could take
a look at the datasheet and give me some guidance
I´d really appreciate it.
Thanks !!
