Abstract
Fully integrated frequency-phase generators
for a 6-18GHz wide-band phased-array receiver element are
presented that generate 5-7GHz and 9-12GHz first LO
signals with less than -95dBc/Hz phase noise at 100kHz
offset. Second LO signals with digitally controllable fourquadrant phase- and amplitude spread with better than 3°
resolution are generated and allow removal of systematic
reference clock skew as well as accurate selection of the
received signal phase. This frequency- and phase generation
scheme was successfully demonstrated in a 6-18GHz receiver
system configured as an electrical 4-element array
