Communication transmission system and power detection method thereof
First Claim
1. A communication transmission system with a power detection function, comprising:
- a power detection circuit, for detecting a power on an output port of the communication transmission system and producing a feedback signal; and
an RF module, connected to the power detection circuit for receiving the feedback signal in order to adjust the output power, wherein the power detection circuit is built to be independent of the RF module for directly detecting the power on the output port of the communication transmission system.

Abstract
A communication transmission system is applied to an application device and includes a power detection circuit, and a radio frequency module. The power detection circuit is used for detecting the power on the output port of the communication transmission system, and for producing a feedback signal. The radio frequency module is connected to the power detection circuit for receiving the feedback signal so as to adjust its output power. In addition, the power detection circuit is built to be independent of the RF module for directly detecting the power on the output port of the communication transmission system which represents the actual power of the application device, thereby achieving the purpose of outputting a more stable and accurate output power through the RF module.

9. A power detection method for a communication transmission system including an RF module and a power detection circuit, the method comprising steps of:
-
producing an output power through the RF module; and detecting the power of an RF antenna in the communication transmission system through the power detection circuit so as to produce a feedback signal to the RF module, wherein the power detection circuit is independent of the RF module for directly detecting the power of the RF antenna in the communication transmission system, thereby the RF module is capable of receiving the feedback signal for adjusting the output power. - View Dependent Claims (10, 11, 12)
