More Information
Summary:A radio frequency module includes a radio frequency integrated circuit (RFIC) to input or output a base signal and a radio frequency (RF) signal having a higher frequency than the base signal, a wiring via extending upward from the RFIC and a feed line electrically connected to the wiring via to provide a transmission path of the RF signal, a second ground layer surrounding the feed line, a first ground layer spaced above the second ground layer, a third ground layer between the second ground layer and the RFIC, a feed-line insulating layer disposed between the first and third ground layers, an IC wiring layer between the third ground layer and the RFIC, electrically connected to the RFIC, and providing a transmission path of the base signal, and an IC insulating layer between the third ground layer and the RFIC, having a higher dielectric constant than the feed-line insulating layer.
