LOW NOISE FREQUENCY REFERENCE, LNFR-100E

FEATURES

 Low environmental sensitivity

 Ultra-low phase noise

 Very low spurious

APPLICATIONS

 Earth station frequency reference

 Phase noise measurements

 Reference frequency generation

 Telecommunications standard

DESCRIPTION

The LNFR-100E is a high performance 10 MHz distributed frequency reference. It contains a 5 MHz SC-cut

ovenized oscillator, a low noise frequency doubler and a distribution amplifier module. The 10 MHz signal is

distributed by the distribution amplifier to provide four 10 MHz outputs on the back panel. Typical cross

-channel isolation is 70 dB and reverse isolation is typically greater than 75 dB. The distribution module does

not degrade the phase noise performance of the oscillator that is typically –142 dBc/Hz @ Fourier frequency of

10 Hz and –168 dBc/Hz @ Fourier frequency greater than 10 kHz. The LNFR-100E outputs are matched to

50 ohms to obtain better than 25 dB return loss. The LNFR-100E can be phase locked via an electrical tuning

port or by providing an external 10 MHz reference.
