RF POWER TRANSISTOR PACKAGES WITH INTERNAL HARMONIC FREQUENCY REDUCTION AND METHODS OF FORMING RF POWER TRANSISTOR PACKAGES WITH INTERNAL HARMONIC FREQUENCY REDUCTION |
摘要 |
A packaged RF power device includes a transistor having a control terminal and an output terminal and configured to operate at a fundamental operating frequency, an RF signal input lead coupled to the control terminal, and an RF signal output lead coupled to the output terminal. A harmonic reducer is coupled to the control terminal and/or the output terminal of the transistor and is configured to provide a short circuit or low impedance path from the control terminal and/or the output terminal to ground for signals at an Nth harmonic frequency of the fundamental operating frequency, where N>1. The device further includes a package that houses the transistor and the harmonic reducer, with the input lead and the output lead extending from the package. Multi-chip packages are also disclosed. |
