Front end parallel resonant switch |
| 摘要 |
A front end parallel resonant switch is disclosed. In an exemplary embodiment, an apparatus includes an inductor and a capacitor configured to couple a first RF transmission to an antenna, and at least one switch configured to connect the inductor to the capacitor to form a matching network when transmitting the first RF transmission from the antenna, and to connect the inductor to capacitor to form a parallel resonant circuit when transmitting a second RF transmission from the antenna. |

1. An apparatus comprising:
an inductor and a capacitor configured to couple a first RF transmission and a second RF transmission to an antenna; and at least one switch configured to connect the inductor to the capacitor to form a matching network when transmitting the first RF transmission from the antenna, wherein the capacitor has a first capacitor terminal that is connected to the antenna, and the at least one switch configured to directly connect a first inductor terminal to the first capacitor terminal to form a parallel resonant circuit when transmitting the second RF transmission from the antenna. |
