PIN FUNCTIONS

Output pin of LNA. Output biasing

and matching required as it is an open

collector output.

Supply voltage pin of regulator mixer

block.

Input pin of RF mixer. 1575.42 MHz

band pass filter can be inserted between

pin 1 and mixer input.

Ground pin of RF mixer cell.

This is a current mode charge pump

output for connection to a passive RC

loop filter for driving the external varactor

diode of 1stLO-OSC.

Supply voltage pin of the phase detector

charge pump.

Ground pin of regulator reference cell.

UPB1007K

Pins 6 & 7 are base pins of the differential

amplifier for 1st LO oscillator. These pins

should be equipped with LC and varactor

circuits to oscillate at 1636.8 MHz.

Supply voltage pin of differential amplifier

for 1st LO oscillator circuit (VCO).

Ground pin of phase detector charge

pump.
