TFF11115HN

Low phase noise LO generator for VSAT applications

Rev. 1 — 24 March 2011

Product data sheet

1. General description

The TFF11115HN 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 11.30 GHz to 11.80 GHz

Input signal 44 MHz to 738 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
