The circuit features a tuning range from 2.24 GHz to 2.45 GHz and a phase noise of -82 dBc/Hz at 1 kHz offset. System level irradiation testing is conducted using high energy mixed-field radiation. First tests show excellent long-term stability of the circuit with no significant degradation up to an 1 MeV equivalent fluence of 8E+11cm-2.enCOTSphase-locked loopradiation effectsSEEsynthesizerTIDConference Paper10.1109/TWIOS.2018.8311400Other
