A variety of optional prime power interfaces to three-phase AC sources worldwide are available. Power supplies, Control Logic Module, and cooling subassemblies are common to all of the amplifiers in the MX9000 Series and use connector interface design throughout for easy and straightforward accessibility. The RF circuit includes a coaxial input interface, input isolator, solid state intermediate power amplifier with electronic attenuator, Klystron tube, arc detector, output isolator and waveguide interface including filters and couplers. Subassembly The MX9000 uses a uniquely designed regulated beam supply to provide stable and reliable operation and minimum phase noise.
Regulation is provided by an electro-mechanical line regulator circuit.
This field-proven circuit of minimal operating components provides unparalleled reliability and performance. A unique beam transformer filter circuit provides suppression of noise generating elements resulting in minimal phase noise on the amplified output signal. A power factor of better than 0.9 assures the most effective use of the prime power source. The blower provides proper cooling airflow for prime power source frequencies of 47 to 63 Hertz. A separate, single- phase blower provides cooling for the beam supply and other cabinet subassemblies.
