SA8025A Datasheet (Philips) - Low-voltage 1.8GHz fractional-N synthesizer

SA8025A, Low-voltage 1.8GHz fractional-N synthesizer

The SA8025A is a monolithic low power, high performance dual frequency synthesizer fabricated in QUBiC BiCMOS technology.

The SA8025A is an improved version of the SA8025, suitable for narrow band systems like the Japan Personal Digital Cellular (PDC) system.

The new design improves the performance
