The 30 m antenna at the DLR site in Weilheim is to be made capable of transmitting in the X-band for future project support. The frequency range is: 7.145 - 7.235 GHz with an input power of approx. 0 dBm (+/- 10 dB). The…
refore a 5 kW (P1dB) SSPA (solid-state power amplifier) is required. This power should be available at the output flange. A suitable system architecture should ensure that the unit is redundant in itself and that defective amplifier stages can be easily replaced. If an amplifier stage fails, the sys
tem should ideally be able to compensate for this loss, or at least remain in operation with reduced power. The failure of an electrical component (including preamplifiers) must not result in a total system failure. It must be possible to c
