POWER SUPPLY USING VSAT SSPA

摘要

a constant current source 5 established in an interior apparatus; a coaxial cable 2 for supplying constant current outputted from the constant current source 5; a relay 8 for switching an input stage of the SSPA(Solid State Power Amplifier:4) established in an exterior apparatus; a parallel regulator 7 connected to the input stage of the SSPA 4 in parallel; a relay controlling current detecting means 9 connected to the parallel regulator 7 to convert a current remaining on the SSPA into a voltage, comparing predetermined counting current with related voltage, controlling the relay to automatically be open when exhausting the current below the value estimated from the SSPA 4.
