MODEL HX3400
8MHz to 6.4GHz Phase Detector
ULTRA LOW PHASE NOISE

• Operation from 8MHz to 6.4GHz
• Phase Noise of -165 dBc/Hz
• LO Power +13dBm
• Proprietary IF Circuitry
• High Carrier Suppression

SUMMARY
The Holzworth HX3400 Phase Detector was designed with an emphasis on making phase noise
measurements and to be used in analog phase locked loops where performance is a priority. The
HX3400 uses a proprietary IF circuit that maintains optimal signal to noise ratio, improving the
performance over standard phase detectors typically by 3dB to 6dB.
The HX3400 Phase Detector helps take the guess work out of phase noise measurements with fully
characterized and guaranteed performance. Holzworth products are 100% final performance
tested for phase noise verification1.
