||||
| Harmonic Output | 50 dB below rated output | |||
| Intermodulation distortion (IMD3) | - 43 dB @ 25% power output - 37 dB @ 50% power output - 33 dB @ 100% power output Using SDR with predistortion mode: -47 dB @ full output |
|||
| Tube | Eimac 4CX3000A | |||
| Input network | 1:4 Transformation, 200 Ohm, 400 W HF Resistor, Tube Input Reactance Compensation & Neutralization for each Band | |||
| Output network | Variable roller inductor 15 uH, Caps: PLATE: 500pF vacuum variable 15 KV + 470 pF fixed & LOAD : 1500pF vacuum variable 4 KV + 1500 pF fixed | |||
| Computer control | Plate current (every 5 msec), SWR, all switching functions, no relais switching under power conditions, soft start inrush, 10 sec delay time for full power, 2 speed turbine & axial blower Stabilized screen and well regulated grid supply for +ve and -ve currents as well as current limiting to protect the tube and minimize the IMD. It is impossible to override the screen and grid dissipation at any working conditions. |
