yea my drive is 100mW max .. but iv read that 60mW is the lowest IMD power out setting .... that's almost perfect ....for driving 2 ...
60mW divided to two devices is about +15dBm each, which is just over the rated
maximum limit. With a resistive divider (50 ohm resistor in series with each input,
giving two 100 ohms combined in parallel) that will reduce the drive to +12dBm,
which is just within the rated maximum limit, and should be pretty close to driving
each module into compression.
With a typical gain of 19dB and a target output of, say, 600mW (+27.5 dBm) from
each device to keep good IMD, you still want less than 10 dBm (10mW) drive per
device, so 20mW max (or 40mW with 3dB loss in a resistive divider.)
