Description and Usage

Bias resistor for PCS LNA.

PCS LNA input. Requires a blocking capacitor, which may be used as part of the

input-matching network.

Power supply pin for PCS and GPS 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.

PCS LO input.

GPS LO input.

Ground.

GPS Mixer input.

PCS LO buffer output. Does not require a blocking capacitor.

Negative GPS IF output.

Positive GPS IF output.

Supply voltage for all mixers.

Mixer Ground.

Negative CDMA output.

Positive CDMA output.

Supply voltage for Logic Control Circuits.

PCS Mixer RF input.

LO output buffer enable. Set BUFFEN pin HIGH to power up the PCS LO buffer

output.

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

Power on for PCS. Logic HIGH selects PCS Band.

PCS 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.
