Title:
ARCHITECTURE OF 5G POWER AMPLIFIER SUPPORTING NON-STANDALONE NETWORKING
Document Type and Number:
WIPO Patent Application WO/2021/120243
Kind Code:
A1
Abstract:
Disclosed is an architecture of a 5G power amplifier supporting non-standalone networking. The amplifier comprises: a first amplification group for supporting 5G and 4G frequency bands; a second amplification group for supporting 4G frequency bands; and a third amplification group for supporting 4G frequency bands. The 4G frequency bands supported by the first amplification group, the second amplification group, and the third amplification group can be the same or different frequency bands. The present invention allows integration of amplification groups supporting 4G and 5G frequency bands, enables simultaneous use of 4G and 5G frequency bands in 5G non-standalone networking, reduces the dimensions of power amplifier chips and modules to facilitate integration, and reduces the design complexity and costs of radio-frequency circuits. In addition, the power amplifier of the present invention does not require an additional 5G N41 PA module.
