Operation of a frequency sextupler (X6) as a radio frequency (RF) E-band upconverting transmitter is experimentally demonstrated. An 8-phase-shift keying signal is digitally upconverted to 13.1-GHz ...

A frequency reconfigurable phased array element is presented. The operational band of the single port L/S-band antenna can be selected by modifying the element apertures with p-i-n diode switches. The ...
