We are planning to use the flex900 gnu radio on a project. In
reviewing the schematic it appears to me that the gain is too high in
the transmit path. The AD8349 puts out about 4 dBm. This is followed
by a MGA82563 with a gain of 14, followed by the power amp RF3315 with
a gain of 18. If the amplifiers had no compression this would result
in an output signal of 36 dBm, 4 Watts. The RF3315 has 25 dBm 1 dB
compression point.
What am I missing or is the modulator lightly driven?
Thanks,
