Problems solved by technology

However, the dual-antenna structure using the first antenna 21 and the second antenna 22 requires a relatively high installation space for the communication terminal using the radio frequency circuit of this solution, which is inconsistent with the current trend of thinner and thinner communication terminals.

Embodiment Construction

[0031] refer to image 3 , which is a schematic diagram of the principle of the radio frequency circuit of the present invention Figure 1 . When the radio frequency circuit of the present invention works in the carrier aggregation mode, one end of the M first radio frequency signal terminals D1 of the L×M switch 34 sequentially passes through one end of the L second radio frequency signal terminals D2 and one of the combiner 33 The third radio frequency signal terminal D3, the fourth radio frequency signal terminal D4, a fifth radio frequency signal terminal D5 of the 1×N switch 4, and the connection with the sixth radio frequency signal D6, and the other of the L second radio frequency signal terminals D2 terminal is not connected to the first radio frequency signal terminal D1 of the M channels of the L×M switch 34, that is, the radio frequency signal is transmitted through the path P1 in the figure. Specifically, before the radio frequency signal is transmitted through t...

Abstract

The invention discloses a radio frequency circuit of an LTE carrier wave polymerization technology and communication equipment thereof. The radio frequency circuit comprises at least one L*M switch, a combiner and a 1*N switch. When the L*M switch is in a carrier wave polymerization mode, switch logic of the L*M switch is selectively connected to a radio frequency path of the combiner. During non-carrier-wave polymerization mode work, through an L*M switch device and one 1*N switch, the combiner is bypassed so that performance in a non-carrier-wave polymerization work mode is guaranteed. In the invention, the radio frequency circuit of a new LTE carrier wave polymerization technology is adopted, circuit insertion losses of a communication terminal under the non-carrier-wave polymerization work mode are effectively reduced, simultaneously a large occupation space problem of a plurality of antenna circuits is avoided, and through flexibly applying the L*M switch device, the radio frequency circuit can satisfy more scene applications.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a radio frequency circuit of LTE carrier aggregation technology and communication equipment thereof. . Background technique [0002] In the field of wireless communication technology, Long Term Evolution (LTE) is a Universal Mobile Telecommunications System (UMTS) technical standard developed by the Third Generation Partnership Project (3GPP). Carrier aggregation technology features have been added since Rel.10, and the current LTE protocol version has evolved to Rel.12. According to preliminary statistics on the upcoming Rel.13 version, there are more than 40 LTE frequency bands, the frequency range is from 450MHz to 3800MHz, and the carrier aggregation (Carrier of 2 Inter-band Component Carriers, Inter-band 2CC) There are more than 50 Aggregation (CA) combinations, and there are more than 40 carrier aggregation combinations of 3 Inter-band Component Carriers (Inter-band 3...
