I am trying to schedule a mixed doubles league with 18 teams with rotating partners.  The teams only play for 5 weeks on 9 courts.  For some reason I cannot find a schedule that fits a mixed doubles league with 18 teams.  Any suggestions?

I think you can use the first 5 rounds (rows) of the spouse avoiding schedule below then a players 5 partners will be different and their 10 opponents will be different, but there will be a little overlap.
