MRFIC1502 Datasheet (Motorola) - 1.575 GHz GPS DOWNCONVERTER

MRFIC1502, 1.575 GHz GPS DOWNCONVERTER

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MRFIC1502/D The MRFIC Line Integrated 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 3 silicon bipolar process and is packaged in a low cost surface mount TQFP 48 package.

In addition to the mixers, a VCO, a PLL and a loop filter are integrated on chip.

Output IF is nominally

* ly 1.0 pF; that can be achieved using either a discrete element or a microstrip open circuited stub. The evaluation circuit shown uses a 0.4 pF capacitor. Phase

* locked Loop Design The VCO signal at 1527.68 MHz is divided by 40 to get the second LO frequency of 38.19 MHz. In addition to provi
