NXP's Radio Frequency Integrated Circuit Designed for High-speed Internet Over Satellite Apps

(Product News, 26 Jun 2008)

Manufactured using NXP Semiconductors' proven SiGeC BiCMOS process technology, the TFF1003HN is a fully integrated LO generator RF IC that forms the core of an outdoor transmitter for high-speed Internet in a satellite base station. The TFF1003HN VSAT RF IC features a simple system design that can withstand harsh environmental conditions and allows for improved spectral use. The TFF1003HN incorporates a phase frequency divider, settable main divider and a VCO.

Product features include no DRO based oscillator, no drift enable mixer, based up conversion and optimal spectral use. The divider ratio can be set to 16, 32, 64, 128 or 256, resulting in an input frequency which can be 50, 100, 200, 400 or 800MHz for the 12.8GHz output frequency, and 51, 102, 204, 408 or 816MHz for the 13.05GHz output frequency. With an 204MHz reference source, the phase noise, integrated from 5kHz to 10MHz, is less than 0.7° RMS with 100kHz phase noise density or -100dBc/Hz.
