Embodiment Construction

[0030] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that a manufacturer may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" and "comprising" mentioned throughout the description and claims are open-ended terms, so they should be interpreted as "including but not limited to...". Otherwise, the term "coupled" includes any direct and indirect means of electrical connection. Therefore, if it is described herein that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

A matching network circuit (110) and an associated apparatus (100) are provided. The matching network circuit (110) includes a matching unit (111, MN) coupled between a common path port (Pcom, P in, P out ) and a first path port (P1) of the matching network circuit (110), and an impedance unit (112) coupled between the common path port (Pcom, P in , P out ) and a second path port (P2) of the matching network circuit (110). The common path port (Pcom, P in , P out ) is utilized for connecting the matching network circuit (110) to a common path, the first path port (P1) is utilized for connecting the matching network circuit (110) to a first device (51, DF_AMP, AMP1, AMP(1)) on a first path, and the second path port (P2) is utilized for connecting the matching network circuit (110) to a second device (52, SE_AMP, AMP2, AMP(2), ..., AMP(n)) on a second path. The matching unit (111, MN) is arranged for performing impedance matching between the common path port (Pcom, P in, P out ) and the first path port (P1), and the impedance unit (112) is arranged for performing impedance matching between the common path port (Pcom, P in , P out ) and the second path port (P2).The matching network circuit can maintain high stability of an electronic device under different conditions.

Description

[0001] 【Technical field】 [0002] The present invention relates to impedance matching, in particular to a matching network circuit and related devices. [0003] 【Background technique】 [0004] According to the related art, a conventional impedance matching network can be used to perform impedance matching in a conventional portable electronic device to solve some transmission problems. However further problems may arise such as some side effects. For example, each conventional impedance matching network typically occupies most of the chip area. In another example, where two conventional impedance matching networks are placed on two signal paths associated with each other, it may be necessary to redesign both conventional impedance matching networks because one of the conventional impedance matching networks May affect another traditional impedance matching network. Therefore, a new architecture is needed to improve the impedance matching control of electronic devices to ensu...
