Abstract
4-terminal HEMT-HBT composite devices, based upon monolithically integrated HEMT-HBT technology and configured in various topologies, are useful in a wide range of applications which currently utilize discrete MMICs. In particular, the 4-terminal topologies are easily configured as 3-terminal composite devices useful in various 2-port and 3-port MMIC circuit applications, such as low noise-high linearity amplifiers as well as mixers, which provide the benefits of a reduction in size, as well as corresponding cost while providing better performance than utilizing either HEMT or HBT devices individually.
