Going ahead a 2 kW, 352 MHz amplifier system, consisting of eight 270W, indigenously designed, amplifier modules and eight-way novel radial power combiner structures, was put in operation. Complete system with power gain of 60 dB, assembled together with power supplies and real time controller, has been tested for more than 3 months.
