Description and Usage

Bias resistor for Cell LNA. For typical bias use a 390 ohm resistor to ground which set the bias current for HGHL

mode.

Cell LNA input. Requires a blocking capacitor and an L-C (shunt C/series L) matching network for optimum gain,

intercept and noise performance.

Cell LNA emitter-ground. The LNA emitter ground should be grounded immediately to the ground-plane to reduce

stray inductance and capacitance that may affect performance.

Power supply pin for GPS and Cell LNAs. Bypass with a capacitor as close to the pin as possible.

GPS LNA input. Requires LC match.

GPS ground.

Supply voltage for LO buffers.

GPS LNA output.

Cell LO input.

GPS LO input.

GPS Mixer input.

Cellular LO buffer output. Internally matched to 100ohms. Does not require a blocking capacitor.

Negative GPS IF output.

Positive GPS IF output.

Supply voltage for all mixers.

Mixer Ground.

Negative Cell Mixer output.

Positive Cell Mixer output.

Supply voltage for Logic Control Circuits.

Cell RF input to Cell CDMA mixer.

Cell LO output buffer enable or GPS enable. Set BUFFEN/GPS pin HIGH to power up the Cell LO buffer output

when Cell band is selected. When both Gain and LIN are low, set BUFFEN/GPS pin HIGH to power up the GPS

application.

Logic input for high or low linearity. Logic HIGH selects High Linearity

Gain Select Logic input for Cellular band. Logic high selects High Gain.

Cell LNA output. Requires a pull-up inductor to Vcc and a series blocking capacitor, which can be used as part of the

output-matching network.
