  • High power MMIC devices having bypassed gate transistors
    Patent number: 9947616
    Abstract: Monolithic microwave integrated circuits are provided that include a substrate having a transistor and at least one additional circuit formed thereon. The transistor includes a drain contact extending in a first direction, a source contact extending in the first direction in parallel to the drain contact, a gate finger extending in the first direction between the source contact and the drain contact and a gate jumper extending in the first direction. The gate jumper conductively connects to the gate finger at two or more locations that are spaced apart from each other along the first direction.
    Type: Grant

  • High power Doherty amplifier using multi-stage modules
    Patent number: 7193473
    Abstract: A high power Doherty RF amplifier utilizes multi-stage amplifier modules for both the main amplifier and the peak amplifiers. In one embodiment of a two way two stage amplifier, the first stage of each amplifier module can include signal pre-distortion whereby the first stage compensates for distortion in both the first and second stages. The design is simple and results in a high efficiency amplifier with high gain. In one embodiment, a commercially available CREE PFM19030SM power module is used in both the main amplifier and the peak amplifier.
