Description
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). Therefore 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 system 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 change a replacement module quickly (ideally during operation). A suitable waveguide switch and a dummy load should also be part of the system (these do not necessarily have to be supplied by the HPA manufacturer). Due to the limited space available, the form factor plays an important role. Ideally, the 5 kW system should be able to be accommodated in a 19'' rack unit. Furthermore, the system should be designed in such a way that it can …
