IDP revenue increased $104.2 million, or 13.2%, in fiscal 2019, compared to fiscal 2018, primarily due to higher demand for our base station products.
IDP operating income increased $31.6 million, or 13.4%, in fiscal 2019, compared to fiscal 2018, primarily due to higher revenue, partially offset by lower gross margin (which was negatively impacted by lower factory utilization).
