Abstract
A high-frequency transmission module includes a first chip, a second chip, and a conductive wire. The first chip includes a first top surface and a number of pads arranged along a periphery of the first top surface. The pads include a first bonding pad. The second chip includes a second top surface and a second bonding pad on the second top surface. The second chip is positioned on the first top surface such that the pads are uncovered by the second chip and the second bonding pad is mostly closed to the first bonding pad. The conductive wire bonds to the first bonding pad and the second bonding pad to electrically connect the second chip to the first chip and is configured to transmit high-frequency signals between the first chip and the second chip.
