Abstract :
Photonic millimeter-wave generation and long-term operation for the high-frequency radio interferometer are reported. The photonic millimeter-wave generator is installed in an antenna for the antenna holography system which measures the antenna surface accuracy. The photonic millimeter-wave generator is under continuous running more than 2 months.The operation frequency is 103.97 GHz. Undesired signals are suppressed to less than -30 dB.
