The antenna on the BCM20737S SiP module is internal, so you cannot detach it from the SoC die that is built into the SiP packaging.
Many have achieved FCC certification in the past with this device and others in the 2073XS family, and this feature has never been required.
Have you provided links to the following documents to your certification house?
Can you please discuss with the lab - why they need to reassess the conductive output power? The module has LMA grant, which means that it only needs spurious emissions testing in an equivalent host via a C2PC submission.
Thank you very much. The lab now agrees that we can send in samples without modification.
