Electronic module for providing bias voltage for antenna matching circuit and note computer

Abstract

The invention provides an assisting electronic module for providing bias voltage to an antenna matching circuit. The electronic assisting module includes an electronic device, a control unit and a voltage supply circuit. The electronic device is an active component, and the control unit is used to receive an input signal, where the input signal includes specific frequency information and input data transmitted to the electronic device. The control unit is used to separate specific frequency information of the input signal from the input data. The voltage supply circuit is used to receive specific frequency information and generate bias voltage to the antenna matching circuit based on the specific frequency information.

Description

technical field [0001] The present invention relates to a circuit design in a notebook computer, and in particular to an auxiliary electronic module located in the panel area of ​​the notebook computer and the notebook computer, wherein the auxiliary electronic module is used to provide a bias voltage Matching circuit to the antenna located in the panel area. Background technique [0002] At present, the Wireless Wide Area Network (WWAN) technology used to browse the Internet has become more and more popular among the public, and electronic devices embedded with wireless wide area network functions have also become one of the necessary mobile devices. element. However, in order to meet the trend of thinner and smaller electronic products, the design of the antenna must be smaller and smaller, but unfortunately, the small antenna that supports multiple frequency bands at the same time is limited by its physical limitations, so it cannot obtain better antenna performance . ...

AI Technical Summary

Problems solved by technology

[0010] The notebook computer 200 not only needs to redesign the wireless wide area network module 230, so that the wireless wide area network module 230 has an extra connector 240 to connect with the antenna matching circuit 210, but the connecting line 250 must also share the connection in the pivot 260 with other connecting lines. space, resulting in overcrowded space within the pivot 260

All in all, the traditional notebook computer with antenna matching circuit has the problems of high manufacturing cost and difficult manufacturing due to the above reasons.
