  • Patent number: 10224291
    Abstract: A high frequency semiconductor device package includes a metal plate, a frame body, a first lead part, a second lead part, a first conductive layer, and a second conductive layer. The frame body includes a first frame part made and a second frame part. The first frame part has a lower surface bonded to the metal plate. The first frame part has an upper surface including a first region and a second region. The first lead part protrudes outward along a line passing through a central part of the first region and a central part of the second region in plan view. The second lead part protrudes outward along the line in plan view. The first conductive layer includes a first stripe part and a first connection part. The second conductive layer includes a second stripe part and a second connection part.

  • Patent number: 9887676
    Abstract: A high frequency semiconductor amplifier includes a package base part, and a monolithic microwave integrated circuit. The package base part includes a metal plate provided with an attachment hole, a frame body bonded to the metal plate and provided with an opening, a first lead part, and a second lead part. The monolithic microwave integrated circuit is provided with a first amplification element and a second amplification element. An output electrode of the second amplification element is connected to the second lead part via an output combiner. Each finger electrode of the second amplification element is generally orthogonal to the first line. Each finger electrode of the first amplification element is generally parallel to the first line. The attachment hole of the metal plate is provided in a region lying along a second line generally orthogonal to the first line and protruding outside the frame body.
