Local Oscillator x21 Multiplier 100 MHz Model 310-027023-003 Typical Applications Features Synthesizer Building Block EW ELINT SIGINT Low Spurious less than -60 dBc Superior Phase Noise: -130 dBc/Hz @ 10 kHz Buffered Input High Output +17 dBm drive Level Integral Voltage Regulator Conduction Cooled Lightweight Aluminum Housing General Description The 310-027023-003 Multiplier is a x21 design providing the system designer with a compact, low phase noise building block for reference oscillator multiplication applications. A linear amplifier drives a step recovery diode thereby multiplying an input 100 MHz clock signal by a factor of 21. A pair of selective 3-pole internal bandpass filters along with a pair of linear driver amplifiers help to deliver low spurious response. The unit exhibits very little degradation of input reference signals, multiplying to the desired output frequency while degrading the input phase noise performance by only 28 dB.
