NAME
FUNCTION
A1
GLNAOUT
GPS LNA Output Port. This port requires an external pullup inductor and series blocking capacitor,
which are part of the matching network.
B1
CLNAOUT
CDMA LNA Output Port. This port requires an external pullup inductor and series blocking capacitor,
which are part of the matching network.
C1
GLNAIN
GPS RF Input Port. Requires a blocking capacitor.
D1
GND
Ground
A2, A4
GIF+, GIF-
GPS Differential Output Port. Requires pullup inductors and blocking capacitors, which are used as
part of the matching network.
B2
G1
Logic Input (Table 1)
C2
RBIAS
Bias Setting Pin. The DC voltage at this pin is a bandgap voltage (+1.2V). For nominal bias, connect
47k
resistor to ground. The value of this resistor can be adjusted to alter the linearity of the LNAs and
mixers in all modes. See Figures 2 and 3 for resistor switching application circuits.
D2
CLNAIN
Cellular RF Input Port. Requires a blocking capacitor.
A3
GMIXIN
GPS Mixer Input Port. Requires a series blocking capacitor.
