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 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 filt

1.7 GHz/ 2.0 GHz LOW-POWER TWO-MODULUS PRESCALER DIVIDED-BY-64/65, 128/129

DESCRIPTION µPB1502GR and µPB1502GR(1) are two-modulus prescaler divided by 64/65 or 128/129. This device is designed for mobile communication applications for example 0.8-1.9 GHz cellular and cordless telephones. The ICs operate on low power and therefore are suitable for hand-held, battery-oper
