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.
