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

This abstract first appeared for US patent application 18349997 titled 'RADIO-FREQUENCY MODULE AND COMMUNICATION DEVICE

Simplified Explanation

The patent application describes a radio-frequency module with multiple power amplifiers and filters.

  • The module includes a first power amplifier and a second power amplifier.
  • The first power amplifier amplifies signals in a first frequency band and outputs them.
  • The second power amplifier amplifies signals in a second frequency band and outputs them.
  • The module also includes a switch and multiple first filters.
  • The first filters have pass bands within the first frequency band.
  • The switch can connect the first power amplifier to the first filters.
  • The module also includes a second filter with a pass band within the second frequency band.
  • The second power amplifier is connected directly to the second filter without the switch.
  • The second power amplifier has a higher output power level than the first power amplifier.


Original Abstract Submitted

A radio-frequency module includes a first power amplifier, a second power amplifier, a switch, a plurality of first filters, and a second filter. The first power amplifier amplifies a transmission signal of a first frequency band and outputs the amplified transmission signal. The second power amplifier amplifies a transmission signal of a second frequency band and outputs the amplified transmission signal. The pass bands of the plurality of first filters are contained within the first frequency band. The pass band of the second filter is contained within the second frequency band. The second power amplifier has a greater output power level than the first power amplifier. The first output terminal of the first power amplifier is switchably connectable to the plurality of first filters via the switch. The second output terminal of the second power amplifier is connected to the second filter without the switch interposed therebetween.
