PASSIVE FEEDBACK PATH FOR PRE-DISTORTION IN POWER AMPLIFIERS |
| 摘要 |
Embodiments of the present disclosure describe apparatuses, methods, and systems of front end module (FEM) having a feedback path that includes a passive attenuation network. The passive attenuation network may provide a feedback signal to a receive output port of the FEM that may be used as a basis for predistortion. Other embodiments may also be described and/or claimed. |

1. An apparatus comprising:
a transmit path having a power amplifier to amplify a first radio-frequency (RF) signal for wireless transmission; a receive path having a low-noise amplifier (LNA) to amplify a second RF signal that is received as a wireless transmission; a switch coupled with the transmit path, the receive path, and an antenna terminal, the switch to selectively couple the transmit path or the receive path with the antenna terminal; and a passive attenuation network coupled with the transmit path and further coupled with the receive path, the passive attenuation network to provide a feedback signal based on the first RF signal, wherein the passive attenuation network is coupled with the transmit path through direct physical and electrical contact. |
