DISTRIBUTED 10 MHz FREQUENCY REFERENCE, FEL-10

FEATURES

• High isolation: > 100 dB

• Low harmonic distortion: -45 dBc

• Low phase noise

APPLICATIONS

• Reference frequency generation

• Earth station references

• Phase noise measurements

• Frequency distribution

DESCRIPTION

The FEL-10 is a low noise distributed 10 MHz frequency

reference. The device can be used to provide a stable and

spectrally pure 10 MHz reference. The FEL-10 can be

phase locked via a +/- 5 VDC tuning signal or phase

locked to an external 10 MHz 1VRMS signal. The unit

incorporates a low noise OCXO and the high performance

distribution amplifier module, HPDA. Five outputs are

available with channel to channel and reverse isolation

exceeding 100 dB. The FEL-10 is offered in a stand-alone

rack-mount enclosure with SMA connectors. The optional

PLL module allows locking to an external 10 MHz source.

The PLL module has loss of reference and loss of lock

indicators.
