I'm not sure the entire signal path.? But there is a lot of gain in the power amplifier, about 50 dB or more.
Those switches have an isolation of about 48 dB in the HF range.? So two of them in series (both off) will have about 54 dB.
So you need to add up the gains and the losses in the correct transmit configuration and see if you end up with a negative or positive number.
You want a significantly negative number to make sure gain margin is sufficient to prevent oscillation or gain peaking.
