Equipment

Power Supply The Power Supply should be a low n oise p ower supply. An Agil ent 6623A Tri ple powe r supply with LC filte rs on the output to reduce noise was used in creating the se evaluation bo ard instructi ons.

Signal Generator The Signal Generator should be capable of frequencies and power level required for the part. A Rohde & Schwarz SML03 was used in creating these eval uation board instru ctions.

Phase Noise / Spectrum Analyzer For measuring phase noise an Agilent E5052A is recommended. An Agilent E4445A PSA Spectrum Analyzer with the Phase Noise option is also usable although the architecture of the E5052A is superior for phase noise measurements. At frequencies less than 100 MHz the local oscillator noise of the PSA is too high and measurements will be of the local oscillator, not the device under test.

Oscilloscope The oscilloscope and probes should be capable of measuring the output frequencies of interest when evaluating this board. The Agilent Infiniium DSO81204A was used in creating these evaluation board instructions.
