Output matching network for wideband power amplifier with harmonic suppression |
| 摘要 |
A wideband harmonic trap includes a first resonant tank in the form of a parallel LC circuit, and a second resonant tank in the form of a series LC circuit. The LC circuits are connected to a common input, an output of the parallel LC circuit is connected to a load and to ground via a shunt capacitor, and an output of the series LC circuit is connected to the ground. |

1. An apparatus, comprising:
a first resonant tank comprising: a parallel LC circuit, wherein L represents an inductor and C represents a capacitor; a second resonant tank, comprising: a series LC circuit;a shunt capacitor, wherein the parallel and series LC circuits are connected to a common input, an output of the parallel LC circuit is connected to a load and to ground via the shunt capacitor, and an output of the series LC circuit is connected to the ground to form a wideband harmonic trap optimized from a sixth-order band-stop filter and provides a highest attenuation in a high-frequency pass-band compared to both fourth-order and sixth-order band-stop filters topology. |
