LNA Bias–Setting Resistor Connection. For nominal bias, connect a 24kΩ resistor to ground. The
value of this resistor sets the bias current for HGHL LNAs.
High-Band RF Input. Requires a blocking capacitor which may be used as part of the input
matching network.
Ground Reference for RF, DC and Logic Inputs. Solder the exposed paddle evenly to the circuit
board ground plane.
Low-Band RF Input. Requires a blocking capacitor which may be used as part of the input
matching network.
Band-Select Logic Input. LOW selects high-band (PCS), HIGH selects low-band (cellular).
Linearity-Select Logic Input. See Detailed Description for control modes.
Gain-Select Logic Input. See Detailed Description for control modes.
LO Divider-Select Input. LOW disables LO divider, HIGH selects divider in cellular and FM
modes. See Detailed Description for control modes.
LO Input Port. Requires an external DC blocking capacitor.
PCS LO Buffer Output Port. Internally matched to 100Ω (nominal). Does not require a blocking
capacitor.
Cell LO Buffer Output Port. Internally matched to 100Ω (nominal). Does not require a blocking
capacitor. The output frequency is one half LOIN when LO/2 is floating or HIGH, and equal to
LOIN when LO/2 is LOW.
No Connection
FM Mixer Output Port. Requires pullup inductor and DC blocking capacitor, which may be used
as part of the output matching network.
Power Supply Pin. Bypass with capacitor as close to the pin as possible.
LO Output Buffer Enable. Drive BUFFEN HIGH to power up the LO output buffer associated with
the selected band.
Mixer Differential Outputs. Require pullup inductors and series capacitors which can be used as
part of the output matching network.
Bias Setting Resistor Connection. For nominal bias, connect a 24kΩ resistor to ground. The value
of this resistor sets current for all blocks except HGHL LNA.
Low-Band Mixer Input. Requires a blocking capacitor which may be used as part of the input
matching network.
High-Band Mixer Input. Requires a blocking capacitor which may be used as part of the input
matching network.
High-Band LNA Output Port. Connect a pullup inductor to V
capacitor which may be used as a part of the output matching network.
Low-Band LNA Output Port. Connect a pullup inductor to V
capacitor which may be used as a part of the output matching network.
