Radio frequency circuit module used for radio data transmission and spread spectrum communication

Abstract

A radio frequency circuit module used on radio data transmission and spread spectrum communication is prepared as connecting digital circuit separately to digital interface and DC circuit as well as transceiver for carrying out treatment on digital signal and communication between digital interfaces, connecting DC circuit to digital circuit and transceiver for supplying DC power for them as well as connecting transceiver to radio frequency front-end for converting digital signal to be radio frequency signal.

Description

technical field [0001] The invention relates to a radio frequency circuit module, in particular to a radio frequency circuit module applied to wireless data transmission and spread spectrum communication. technical background [0002] Traditional 2.4GHz RF circuit boards usually have the following problems: [0003] First of all, it is the miniaturization of radio frequency integrated circuits. Traditional 2.4GHz RF circuit boards are usually composed of discrete devices, including microprocessors, transceivers, power supply units, RF front-end units, matching networks, antennas, etc., which are large in size and poor in versatility, which is not conducive to practical use. [0004] Secondly, there is the problem of high power consumption of radio frequency integrated circuits. The traditional 2.4GHz radio frequency circuit has the disadvantages of high power consumption and short battery life, and cannot be used in systems that require long-term standby. [0005] The thi...

AI Technical Summary

Problems solved by technology

Traditional 2.4GHz RF circuit boards are usually composed of discrete components, including microprocessors, transceivers, power supply units, RF front-end units, matching networks, antennas, etc., which are large in size and poor in versatility, which is not conducive to practical use

[0004] Secondly, the high power consumption of radio frequency integrated circuits

The traditional 2.4GHz radio frequency circuit has the disadvantages of high power consumption and short battery life, so it cannot be used in systems that require long-term standby

[0005] The third is the "external activation" problem of the radio frequency circuit

The traditional 2.4GHz radio frequency circuit activation methods are generally built-in "watchdog" circuits, timers, etc., all of which have a certain power consumption and need to consume a certain amount of current, and can only achieve a standby time of 3-6 months. Achieve the design goal of ultra-long standby time
