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. 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. LNFR-100E Users Manual
