Title:
MULTI-BAND LOW-NOISE AMPLIFIER, PHASED ARRAY, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/104762
Kind Code:
A1
Abstract:
The present application provides a multi-band low-noise amplifier, comprising: an input end, a first input matching network, a second input matching network, a first amplifier, and a second amplifier. The input end is coupled to an antenna and is used for receiving an inter-band carrier aggregation signal, the inter-band carrier aggregation signal comprises a first carrier signal within a first frequency band and a second carrier signal within a second frequency band, and the first frequency band is different from and does not overlap with the second frequency band. The first input matching network is coupled between the input end and the first amplifier and is used for impedance matching for the first carrier signal, and the first amplifier is used for outputting the amplified first carrier signal. The second input matching network is coupled between the input end and the second amplifier and is used for impedance matching for the second carrier signal, and the second amplifier is used for outputting the amplified second carrier signal.
