The invention discloses a Sub-6G-LTCC Internet of Things radio frequency front-end microsystem, and particularly relates to the field of radio frequency front ends, which comprises a base band and a communication transceiver chip connected with the base band. The communication transceiver chip and the baseband are used for receiving or transmitting radio frequency signals required in the operation process of the system; the output end of the communication transceiver chip is connected with a power amplifier, and the power amplifier is used for amplifying a required radio frequency signal, so that the radio frequency signal meets the requirement of a receiving range of dynamic change of a system; the output end of the power amplifier is connected with a first filter, and the first filter is used for realizing emission filtering of radio frequency signals and inhibiting out-of-band signals; the output end of the first filter is connected with a duplexer. The power amplifier can be protected, the switching synchronization between the receiving and transmitting links can be ensured, the power amplifier can be prevented from being damaged by the echo of the transmitted signal, and the dual-set antenna is divided into two different modules, so that the problem of PCB decoration can be solved, the power consumption is reduced, and the radio frequency performance is improved.
Description
technical field [0001] The present invention relates to the field of radio frequency front end, more specifically, the present invention relates to a Sub-6G-LTCC Internet of Things radio frequency front end microsystem. Background technique [0002] With the vigorous development of global mobile communications, mobile terminals will continue to evolve from 2G, 3G to LTE networks, and will usher in the 5G era of large bandwidth, high speed, low latency, high reliability, and low power consumption. It is estimated that the per capita traffic will reach 18Gbit in 2019, and the mobile Internet traffic has entered the era of zettabytes. The "Internet of Everything" and "Ubiquitous Perception" drive innovation breakthroughs in smart terminal products to adapt and meet the higher requirements of the network and users. 5G and the Internet of Things will become new engines driving the development of the terminal market. [0003] The main components of terminals currently on the mark...
