I've updated the requirements document on the
U-band receiver web page. This version accounts for text-mode uplinks but that
doesn't change the requirements significantly. I did make assumptions about the
antenna pattern (the same as before) and the text-mode uplink spacing and
bandwidth (these are new). I've allowed for splitting the receiver into two
modules in case this is needed to solve the thermal problem. I've also
changed the requirements for PAVE PAWS interference abatement by assuming that
the SAW filters will be the primary mechanism used. This may allow lower
DC power consumption.
All of the requirements should be verifed by
those interfacing to the receiver.
