LOW NOISE FREQUENCY MULTIPLIER, FS020

DESCRIPTION

The FS020 ultra-low noise frequency doubler can be used with state-of-the-art crystal frequency sources

without degrading phase noise or environmental stability. The FS020 provides double the input frequency

while maintaining spurious signal levels below -50 dBc. The FS020 is ideal for phase lock applications,

frequency synthesis chains and frequency distribution. FS020 doublers are available at user specified input

frequencies from 1 to 500 MHz.

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

APPLICATIONS

• Frequency multiplication

• Phase noise measurements

• Reference frequency generation

• Telecommunications standards
