Optimierung eines SAT-WFR-Verstaerkers Schlussbericht

A conduction cooled 100W/12 GHz TWTA for Satellite application was developed and qualified. The following data could be measured: Frequency Range: 11.7 -12.5 GHz; Saturation Output Power: > 110 W; Phaseshift: < 38 ; AM-PM Conversion: < 4 /dB; Overall Efficiency: > 60%; Mass: < 2600 Gramm. With the TWT TL 12113 and the EPC AT 110 an extremely high weight and high efficient TWTA with unregulated bus voltage is now available.
