Abstract:

The design of a planar integrated Kaband ODU(Outdoor Unit) for satellite commu nicati on terminals is described. In order to realize small size, light weight and low power consumption of the equipment, planar integrated technologies are adopted i n the design of the circuits and structures of ODU. Two prototypes are fabricate d. The technical indexes of the samples satisfy the design requirem ent. The output power is more than 33 dBm. The noise figure is less than 2 .4 dB at roo m temperat ure. The size is less than 130 mm×90 mm×30 mm. The weight is less than 750 g. The test results demonstrate the technology is valid and can meet the engineering ap plications.
