MRFIC1505/MRFIC1505A Integrated GPS
Downconverter
1.575 GHz GPS DOWNCONVERTER
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
MOSAIC 5 is a trademark of Motorola, Inc.
