I'm checking around to see if our Manufacture's Rep in the Bay and internal Regultory team can provide some recommendations.
We have a large number of users here on the forum from that area as well, so I'm hoping one of them can comment.
Below is the contact information for the UL that tested the BCM20732S.
Consumer Technology Division
47173 Benicia Street

I just received additional input from the local Broadcom Manufacture's Rep in the Bay Area, RF Associates.
They felt that a large majority of their customers use either CKC (EMC Testing - EMC Test Lab - EMI testing - EMI test lab - FCC testing - FCC test lab - EMC compliance - RFI testing - RF…) or Bay Area Compliance Labs (Bay Area Compliance Laboratories Corp.).
This should give you a few additional options.
