RADIO FREQUENCY MODULE AND COMMUNICATION DEVICE - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18333099 Titled 'RADIO FREQUENCY MODULE AND COMMUNICATION DEVICE'

Simplified Explanation

The abstract describes a radio frequency module that includes different filter circuits to manage different frequency bands. The first filter circuit is connected to an antenna terminal and a first input/output terminal and allows signals in a lower frequency band to pass through. The second filter circuit is connected to the same antenna terminal but a different input/output terminal and allows signals in a higher frequency band to pass through. The module also includes a band-elimination filter circuit on the second path that attenuates signals in a specific frequency range above the second frequency band. The second filter circuit is an LC filter circuit that uses an inductor and a capacitor.


Original Abstract Submitted

A radio frequency module includes: a first filter circuit disposed on a first path that connects an antenna terminal and a first input/output terminal, and having a passband that is a first frequency band; a second filter circuit disposed on a second path that connects the antenna terminal and a second input/output terminal, and having a passband that is a second frequency band higher than the first frequency band; and a band-elimination filter circuit disposed on the second path and having an attenuation band that is a partial band of a third frequency band that belongs to an unlicensed band ranging from 5 GHz or higher, and is higher than the second frequency band. The second filter circuit is an LC filter circuit that includes an inductor and a capacitor.
