Abstract

Disclosed are a radio frequency splitter and a front-end module. The radio-frequency (RF) splitter is provided. The RF splitter includes a common branch node configured to transfer an RF signal, input from an input port, to at least one of first and second output ports, first and second branch nodes electrically connected between the common branch node and the first and second output ports, first and second series switches configured to control switching operations to electrically connect the common branch node and the first and second branch nodes to each other, first and second inductors electrically connected between the common branch node and the first and second branch nodes, a resistor electrically connected between the first and second branch nodes, and first and second shunt switches configured to control switching operations to electrically connect the first and second branch nodes and the resistor to each other.

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2020-0044727 filed with the Korean Intellectual Property Office on April 13, 2020, the entire disclosure of which is incorporated by reference for all purposes at this. technical field [0002] The following description relates to a radio frequency (RF) splitter and front-end module. Background technique [0003] In order to increase the communication speed of a wireless local area network (WLAN), communication technologies with wide bandwidth and high throughput and standardization of communication protocols are continuously being performed. Wi-Fi 6 (802.11ax) applying technologies such as Orthogonal Frequency Division Multiple Access (OFDMA), Multi-User Multiple-Input Multiple-Output (MU-MIMO) for high-density / high-efficiency WLANs is currently being implemented (below standardization) to achieve not only an increase in communication speed but also further improvement in communicati...
