MICROWAVE AND MILLIMETER WAVE CIRCUIT

摘要

Embodiments of the present invention provide a micro and millimeter waves circuit, including: a multi-layer circuit board, a heat substrate, and a circuit module. The multi-layer circuit board is opened with a window. The heat substrate includes a base. The multi-layer circuit board is attached to the base. The heat substrate further includes a projecting part extending from the base into the window of the multi-layer circuit board. The circuit module is received in the window and placed on the projecting part. The circuit module is electrically connected with an outer conductor layer of the multi-layer circuit board.
