LOW NOISE FREQUENCY MULTIPLIER, FS040

FEATURES

• User specified input frequency

• Ultra-low phase noise: -143 dBc/Hz @ 1 Hz

-170 dBc/Hz @ 1 kHz

-176 dBc/Hz @ 100 kHz

• Very low spurious: -50 dBc

DESCRIPTION

The FS040 ultra-low noise frequency multiplier can be used with state-of-the-art crystal frequency sources

without degrading phase noise or environmental stability. The FS040 provides four times the input

frequency while maintaining spurious signal levels below -50 dBc. The FS040 is ideal for phase lock

applications, frequency synthesis chains and frequency distribution. FS040 multipliers are available at user

specified input frequencies from 1 to 50 MHz with a 10% bandwidth. The FS040 is available in a milled

aluminum enclosure with dimensions of 4.0” X 5.1” X 1.1” and SMA connectors. The module requires

+12 to +15 VDC at 150 mA.

SPECIFICATIONS

All tests done at +13 dBm input unless otherwise specified.

APPLICATIONS

• Frequency multiplication

• Phase noise measurements

• Reference frequency generation

• Telecommunications standards
