Title:
ANTENNA MODULE AND FRONT END CIRCUIT FOR USE IN SAME
Document Type and Number:
WIPO Patent Application WO/2024/014065
Kind Code:
A1
Abstract:
An antenna module (100) comprises high-frequency circuits (105A, 105B) and a front end circuit (140) that transmits signals between a BBIC (200) and the high-frequency circuits (105A, 105B). The front end circuit (140) includes switches (141A, 141B) that are connected to the high-frequency circuits (105A, 105B), switches (143A, 143B) that are connected to the BBIC (200), and branch elements (142A, 142B). The front end circuit (140) switches the switches so as to switch between a first state in which signals are transmitted between the BBIC (200) and one of the high-frequency circuits (105A, 105B) and a second state in which signals are transmitted between the BBIC (200) and both of the high-frequency circuits (105A, 105B).
