Embodiment Construction

[0051] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. . Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] In the prior art, the PA and the VCO are usually integrated on the same chip, and the PA will generate harmonic signals during operation. Since the PA and the VCO are integrated on the same chip, the harmonic signals will flow to the VCO, thus affecting the normal operation of the VCO. In the embodiment of the present invention, the harmonic suppression module connected to the power amplifier module can suppress the ...

Abstract

The invention discloses a wireless signal transmitting device with harmonic suppression and a harmonic suppression method, which are used for solving the problems of cost and power consumption caused by a PA harmonic suppression technology in the prior art. The transmitting device can comprise a power amplification module, a harmonic suppression module and an antenna module, and the power amplification module is used for inputting a radio frequency signal and outputting an amplified radio frequency signal; the harmonic suppression module is used for suppressing a to-be-suppressed harmonic signal of the amplified radio frequency signal and generating a radio frequency signal after harmonic signal suppression; and the antenna module is used for sending the radio frequency signal after the harmonic signal suppression to a signal receiving device. Compared with the prior art, in the embodiment of the invention, the harmonic suppression module is used for suppressing the harmonic signal, so that the power consumption of the VCO inductor does not need to be increased or a special structure of the VCO inductor does not need to be used for suppressing harmonic interference, the quality factor of the inductor can be improved, and the efficiency of the inductor is further improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a wireless signal transmitting device with harmonic suppression and a harmonic suppression method. Background technique [0002] With the rapid development of the Internet of Things, whether in industry or academia, Internet of Things technology is an important research hotspot at present, including the design research of its necessary components of wireless transceivers. The wearability of IoT devices, long-term data transmission, stability, reliability, etc. are necessary conditions, which put forward higher requirements for wireless transceivers to realize IoT communication, which must be miniaturized and low power consumption. This requires that the circuit structure of the wireless transceiver has a sufficiently high integration level and a sufficiently small power consumption. At this time, the selection of a suitable wireless communication technology becomes very...
