TFF1044HN中文资料Integrated mixer oscillator PLL for satellite quad LNB数据手册恩XP规格书

描述 Description

The TFF1044HN is a 10.70 GHz to 12.75 GHz Ku band down converter for use inuniversal quad and quattro Low Noise Block (LNB) in satellite receiver systems. Thedevice features two RF inputs (two polarizations) and four IF outputs (up to 4 active IFpaths). It integrates bias generation and control for the required external LNA stages,image rejection filtering, LO generation, down-conversion mixers, IF amplifier stages,voltage and tone detection on each IF output (for polarization and band selection) andthe 4 (IF channels) x 4 (2 polarizations, 2 bands) IF matrix switch. For flexibility,the gain can be controlled in three discrete stages, the polarization of the RF inputscan be swapped and the second stage LNA biasing control can be switched from pHEMT toBJT configuration.
