FRONT END SYSTEM WITH LOSSY TRANSMISSION LINE BETWEEN FRONT END MODULE AND TRANSCEIVER

摘要

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.

主权项

1. A wireless communications system comprising:
a transceiver; a lossy transmission line communicatively coupled to the transceiver; a first terminal communicatively coupled to the transceiver through the lossy transmission line; a second terminal communicatively coupled to an antenna; and a front end module disposed between the first terminal and the second terminal, the front end module configured to amplify a signal received at the first terminal or the second terminal.
