ADMV8818 and ADMV8913 bi-directional?

Hello,

I wanted to know if the ADMV8818 and ADMV8913 tunable filter chips are bi-directional? The datasheets don't explicitly say, but the s-parameter data seems to suggest so. I wanted to double check before laying out a design which uses RF2 as an input.

Thanks in advance,

Sami
