Abstract :
Summary form only given, as follows. The paper presents the experimental results regarding the combination of a software-defined multi-Gbps modem and a high power amplifier (HPA) when tested with standard DVB-S2 and LDPC rate 9/10 FEC codec. The modem supports waveforms including QPSK, 8-PSK, 16-APSK, 32-APSK, 64-APSK, & 128-QAM. The broadband HPA is a space qualified TWTA, which has a passband 3 GHz at 33 GHz, output power 200 watts & efficiency 60%. The system enabled an unprecedented data rate at 20 Gbps with BER of 10-9.
