MODE
Pin can be grounded or left open-circuit.
GPS LNA Input. Requires a DC-blocking capacitor, which can
be used as part of the matching network.
Operating Mode Logic Input. Sets device operating modes.
See Table 2 for details.
GPS LNA Output. Internally matched to 50 ? including an on-
chip DC-blocking capacitor.
Operating Mode Logic Input. Sets device operating modes.
See Table 2 for details.
Internally Connected. Do not make connections to this pin.
GPS Mixer Input. Requires a DC-blocking capacitor, which
can be used as an interstage coupling capacitor.
Operating Mode Logic Input. Sets device operating modes.
See Table 2 for details.
Bias Setting Pin. For nominal bias, connect a 20k ? resistor to
