Feed system, being the primary radiator, plays a fatal role in antenna systems. Therefore, it’s regraded as the heart of antenna. It is used to provide effective radiation for parabolic antenna, sort the electromagnetic wave reflected from refelctor to keep their Pol. direction same, do impedance conversion so that the electromagnetic wave in the feed transferred from Circular waveguide transmission to rectangular waveguide transmission. Thus, the antenna efficiency can be improved.
Features:
C-band&Ku-band diplexer is composed of orthomode coupler, broadhand 90° phase shifter, low pass filter. This diplexer provides public receiving and transmitting carrier channel for antenna feed system and does frequency demultiplication and polarization discriminition treatment to the receiving and transmitting carrier so that assure the main performance specification and normal work of antenna feed system and reduce the interference and error rate of satellite communication system.
