You should really be using the transverter interface so that it is impossible to have 10W emerging from that port, however, what I have done in the past with radios without a transverter output, like the FT817, is to fit a 20 dB attenuator in line. The system for 10GHz usually has more than enough gain to overcome this by the time the low noise pre-amp is added. In fact, if you arrange it properly and use a common TX/RX mixer you then do not need TX/RX switching at the IF side and the dangers of blowing up the transverter by not correctly switching TX/RX are over.
Beware of the transverter interface, it appears to have some problems, at least mine does, at low power levels.
