A GaAs numerically controlled oscillator (NCO) has been designed and fabricated in 1- mu m GaAs E/D MESFET direct-coupled FET logic (DCFL). The NCO has been designed for spaceborne applications emphasizing low power and radiation tolerance. The NCO will be utilized for both direct digital frequency synthesis and direct digital phase modulation applications. The device contains all the necessary functions to perform frequency and phase synthesis using only an external digital-to-analog converter. The device has been fabricated and is fully functional.
