[GS] Research Tx PA alternatives
The ground station UHF Tx PA selecetd in CDR is unavailable currently. Thus, we need to investigate alternative solutions such as out-of-the-box solutions, stand-alone ICs or MOSFETs (that will require to design a PCB as well).
The things that contrain us are:
- Cost Budget
- Link Budget
The current link budget expects a PA of 13W output power, resulting along with the helical antenna of 12 dBi to an EIRP of around 22 dBW (with losses). Given this EIRP, we result in a reasonably high link margin of 12 dB in the Science Mode worst case (Table XXI, DDJF_LINK_ARPT). Adjustments could be made potentially to the antenna as well to reach a desirable EIRP if we face difficulties in finding a PA component of the desirable output power.
