MOTOROLA RF/IF DEVICE DATA
This integrated circuit is intended for GPS receiver applications. The dual
conversion design is implemented in Motorola’s low–cost,
high–performance MOSAIC 5
silicon bipolar process and is packaged in a
low–cost surface mount LQFP–48 package. In addition to the mixers, a
VCO, PLL, Crystal Oscillator, A/D converter and a loop filter are integrated
on–chip. Output IF is nominally 4.1 MHz.
105 dB Typical Conversion Gain
2.7 V Operation
28 mA Typical Current Consumption
Low–Cost, Low–Profile Plastic LQFP Package
