TFF11142HN

Low phase noise LO generator for VSAT applications

Rev. 1 — 28 March 2013

Product data sheet

1. General description

The TFF11142HN is a K_uband frequency generator intended for low phase noise Local

Oscillator (LO) circuits for K_uband 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 14.13 GHz to 14.42 GHz

 Input signal 55 MHz to 901 MHz

 Divider settings 16, 32, 64, 128 or 256

 Output level 6 dBm; stability 2 dB

 Third or fourth order PLL

 Internally stabilized voltage references for loop filter

3. Applications

 VSAT up converters

 Local oscillator signal generation
