A modular package may be utilized to mount an RF system-on-chip in one of plural configurations, such that the same modular package may be utilized to enable plural device formats, while reducing the amount of RF testing needed to change device formats. In one configuration, a surface mount device is mounted onto a first surface of a board, and the board is directly surface mounted onto a base board. Here, the base board includes a hole for accommodating the surface mount device, providing a thin device format. In a second configuration, a spacer is mounted onto the first surface of the board, such that a gap is provided between the board and the base board for accommodating the surface mount device, providing a relatively thicker device, but providing additional surface area where the hole otherwise would be, reducing the device size.
