Abstract
A high-speed serrodyne digital frequency translator utilizes a digital phase-shifter, for example, of series coupled Schiffman type cells, which have reference and delay paths which are switched by three-terminal devices of the gallium arsenide FET type. No bias voltages are used and the FETS are driven by the output of a binary divider network which in turn is composed of GaAs FETS as active elements. Thus switching in the picosecond range results.
