oncerning the UBITX: the PA delivers 26 dB of gain, so for 10 W output the input power for the PA is +40 dBm - 26 dB = +14 dBm This power can be easily achieved with only one MMIC e.g. one of the GALI amps--- or a discrete verions (BS170)?
You need more gain than that from the mixer to output.? About 30db to 36db.? Also the driver need to deliver +14dbm but I'd
strongly suggest enough headroom to hit 20dbm.? You want to hit 10W but not have a stage limiting at 10W.
