The antenna switch for the SIP device is defined as a component in the board meta data, similar to the antenna switches for other boards (/launchpads) with this feature.
For the SIP package, the antenna switch is a component embedded in the device package, and is present regardless of board mount. That is, regardless of selection of "device" or "board" in SysConfig. In this case, the antenna switch is not a board component.
The antenna switch should be removed as a defined board meta data component, and any antenna switch logic will be handled internally by the RF module.
