Specific embodiments of the present application have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

First, the terms involved in the present application will be explained:

the ENDC or E-UTRAN New Radio-Dual Connectivity is a non-independent (NSA) function, which allows a mobile device (UE) to connect to both 5G and 4G (LTE) networks at the same time, so that an operator can use Radio resources of both network technologies at the same time, and can understand that the 4G and 5G dual connectivity is compatible.

Frequency band: is a specific frequency range in which the frequency is divided from very low frequencies to very high frequencies, each band having its upper and lower limits. In the radio frequency spectrum, a frequency band is also referred to as a frequency.

Radio frequency front end module: two or more than two discrete devices such as a radio frequency switch, a low noise amplifier, a filter, a duplexer, a power amplifier and the like are integrated into a module, so that the integration level and the performance are improved, and the size is miniaturized.

Double Pole Double Throw (DPDT) switch: is an electromechanical switch which can be constructed by adding a pole to a Single Pole Double Throw (SPDT) switch.

Single pole double throw switch: the power switch consists of a movable end and a stationary end, wherein the movable end is a so-called knife and is connected with the incoming line of a power supply, namely one end of the incoming line, and is also generally connected with a handle of the switch; the other two ends are the two ends of the power supply output, namely the so-called stationary ends, which are connected with the electric equipment.

Currently, in the field of mobile communication, 5G is a complex concept, and needs to integrate mobile broadband, internet of things and advanced automation, and all adopt unified standard technologies. In summary, 5G can be divided into three major classes, 5G supporting Internet of things (IoT) applications, 5G using Sub-6 GHz band and 5G using mmWave (millimeter wave). They have different standards and market requirements, requiring more diversified RF radio frequency devices.

In the 5G era, the MIMO frequency bands which are generally required to be supported in international versions are B1/n1, B3/n3, B7/n7, B30/n30, B40/n40, B41/n41, B25/n25, B66/n66 and the like. Since industry regulations, the 4G Band starts with B, e.g., B1, denoted Band1; the 5G band starts with n, such as n1. The 5G NR frequency band can be divided into two types, one is a new frequency band, such as an n77 and an n78 frequency band; the other is the heavy tilling re-fixed frequency band, such as n1, n2, n5, n8, etc. The Re-fixed frequency band is co-frequency with the LTE frequency band, e.g., B1 and n1 are co-frequency. It should be noted that the embodiments of the present application only relate to the re-fixed frequency band.

The introduction of new frequency bands, plus support for MIMO, has resulted in a greater demand for RF radio frequency devices in the 5G age. Meanwhile, on the premise that the structure of the mobile phone is not changed greatly and the frequency band is increased, the requirement for an antenna tuning device is greatly increased, and the mobile phone circuit board is crowded. In addition, 5G brings more complex rf architecture, pursuing lower difference loss and supporting higher output power, the filter performance would be a watershed of overall rf performance.

From the above, the requirements of the 5G development on the radio frequency module, the area consideration of the circuit board, the better 5G radio frequency performance, the more complex 4G carrier aggregation, etc., all represent that the radio frequency devices are increasingly tending to integrate. Generally, the method is divided into four design parts, namely a main set part, a main set MIMO part, a diversity part and a diversity MIMO part. For the design of diversity and diversity MIMO, the diversity function is generally implemented by using a diversity receiving module DRX LFEM ((Diversity Receive LNA Front End Module) of diversity, and the diversity MIMO function is implemented by using an external filter and a low noise amplifier module.

Example 1

The application provides a transmission method of communication signals, which aims to solve the technical problems in the prior art.

a plurality of external multiple-input multiple-output (MIMO) filters 104 (only one is schematically shown in fig. 1) are connected to the diversity receiving module 103 for filtering the independent multipath communication signals.

The embodiment of the application discloses a multi-input multi-output circuit, in particular to a diversity multi-input multi-output circuit, which is a technology adopted in radio communication in the technical field of 5G communication. The transmitting end transmits one or more signals of the same message, and the receiving end recovers the transmitted message by using a selection or combining circuit to obtain a better message quality than any single signal, which is called diversity.

In an alternative example, diversity is generally divided into: frequency diversity, spatial diversity, polarization diversity, angle diversity, code diversity, modulation diversity, etc. The diversity referred to in this case is spatial diversity.

In the embodiment of the application, the radio frequency front-end module integrates two or more than two discrete devices such as a radio frequency switch, a low noise amplifier, a filter, a duplexer, a power amplifier and the like into one module, thereby improving the integration level and the performance and miniaturizing the volume.

In the embodiment of the application, a diversity receiving module DRX LFEM and a separation filter, namely an external multi-input multi-output MIMO filter, can be adopted to realize the diversity function and the diversity MIMO function at the same time, and the DRX LFEM is internally provided with a frequency band filter, a switch, a low noise amplifier LNA and the like. In addition, the LFEM opens multiple switch interfaces, and connects separate MIMO filters to the multiple switch interfaces to multiplex LNAs in the switch interfaces. Therefore, the use of a low-noise amplifier module in the 5G diversity radio frequency front end module can be reduced, the design is further simplified, the cost is reduced, and the area of the ornament is saved.
