TFF11152HN

www.DataSheet4U.com TFF11152HN Low phase noise LO generator for VSAT applications Rev. 1 — 12 July 2010 Objective data sheet 1. General description The TFF11152HN is a Ku band frequency generator intended for low phase noise Local Oscillator (LO) circuits for Ku band VSAT transmitters and transceivers. The specified phase noise complies with IESS-308 from Intelsat. CAUTION This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling. 2. Features and benefits        Phase noise compliant with IESS-308 (Intelsat) in combination with appropriate source LO generator with VCO range from 14.80 GHz to 15.50 GHz Input signal 58 MHz to 969 MHz Divider settings 16, 32, 64, 128 or 256 Output level 5 dBm; stability 2 dB Third or fourth order PLL Internally stabilized voltage references for loop filter 3.
