Abstract:We investigate the externally generation of an LO signal by optical heterodyning, which is then distributed to each of the mixers at every antenna element of a phased array antenna used for standard DVB-S (digital Video Broadcasting-Satellite) reception system. The system1 is presented in Figure 1. The Ku-Band (10.7 GHz ~12.75 GHz) RF signal from the antenna array is amplified and then down converted to IF (950 MHz to 2150 MHz) at the mixer by a 9.75 GHz LO signal generated by optical heterodyning
