TFF11105HN

Low phase noise LO generator for VSAT applications

Rev. 2 — 14 April 2011

Product data sheet

1. General description

The TFF11105HN 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 10.30 GHz to 10.80 GHz

Input signal 40 MHz to 675 MHz

Divider settings 16, 32, 64, 128 or 256

Output level −4 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
