Title:
ANTENNA DIPLEXER CIRCUIT, POWER AMPLIFIER TRANSMISSION MODULE AND MOBILE COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/020015
Kind Code:
A1
Abstract:
Provided in the present application are an antenna diplexer circuit, a power amplifier transmission module and a mobile communication device. The antenna diplexer circuit comprises: a first port, which is used for being connected to a first processing circuit, wherein the first processing circuit processes a first signal; a third port, which is used for being connected to a second processing circuit, wherein the second processing circuit processes a second signal, and the operation frequency of the second signal is lower than the operation frequency of the first signal; a second port, which is used for being connected to an antenna, wherein the first signal and the second signal share the antenna; a first filter, which is arranged between the first port and the second port; a first impedance matcher, which is connected between the first filter and the second port; a second filter, which is arranged between the third port and the second port; a second impedance matcher, which is connected between the second filter and the second port; and a third filter, which is connected between the second port and the ground in a bridging manner.
