摘要： An apparatus comprising a first amplifier, a second amplifier and a control circuit. The first amplifier may be configured to present a first amplified output signal in response to an input signal. The second amplifier may be configured to present a second amplified output signal to provide a shaped signal peaking response in response to the input signal. The first and second amplified output signals are generally combined. The control circuit may be configured to control a ratio between the first amplified output signal and the second amplified output signal. The ratio controls an amount of the peaking response.

摘要： 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.
