Problems solved by technology

[0002] Based on the 5G NR trend, Taiwan MediaTek Co., Ltd. (MTK, MediaTek.Inc) has defined a power amplifier module (L-PAMiF, Low noiseamplifier-Power Amplifier Module with integrated filter), among them, the working frequency of n79 is 4400~5000MHz, however, the working frequency of Wireless Fidelity (WiFi, Wireless Fidelity) 5G is 5150~5850MHz, obviously, n79 is very close to the working frequency band of WiFi 5G. This frequency is called the coexistence frequency. In practical applications, this coexistence frequency will cause serious interference to their respective receivers.
[0003] In order to eliminate interference, frequency division multiplexing (FDM, Frequency division multiplexing) schemes or time division multiplexing (TDM, Time division multiplexing) schemes are usually used. However, the above schemes do not effectively suppress the coexistence frequency, resulting in network performance It can be seen that the power amplifier module in the existing RF front-end architecture has a technical problem of poor network performance when suppressing coexistence frequencies
