Title:
DISTRIBUTION CIRCUIT, RECEPTION DEVICE, AND TRANSMISSION/RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/238502
Kind Code:
A1
Abstract:
The present invention is for reducing the circuit area in a reception device that distributes radio signals. In the present invention, a low noise amplifier comprises an input matching circuit for converting input impedances of a subsequent circuit and an amplification circuit for amplifying radio signals from the input matching circuit. A power splitter comprises a first output matching circuit that converts a first load impedance into a first impedance related to a load impedance ZL of the low noise amplifier, and a second output matching circuit that converts a second load impedance into a second impedance related to the ZL.
