Abstract
Disclosed herein are various examples of architectures, circuits, devices and methods that can be configured to, among other things, improve the efficiency and/or noise figure of signal amplification systems. To achieve this improvement, a front end module is disposed close to a corresponding antenna with a transmission line between the front end module and a transceiver. This results in a bulk of the loss between the antenna and the transceiver occurring between the front end module and the transceiver. A control and/or supply voltage can also be provided to the front end module through the transmission line, reducing or eliminating the need for separate signal and/or control paths to the front end module.
