Single Chip Transmitter with Integrated Up-converter and PLL for Ku-band M2M Applications

摘要

This paper describes a Ku-band up-converter for low cost satellite Machine to Machine (M2M) applications. The up-converter comprises a heterodyne sliding-IF architecture. This converts the baseband input signal (0 - 20 MHz) to the RF output signal (13.75 -14.75 GHz). The necessary Local Oscillator (LO) signals are generated by an on-chip integrated fractional-N PLL. This integration allows for a cost reduction with respect to currently available solutions.
