A novel radio frequency transceiver module

Abstract

This utility model discloses a novel radio frequency transceiver module, including a module body. The module body includes an antenna layer, a transceiver circuit layer, and an isolation layer disposed between the antenna layer and the transceiver circuit layer for isolating and connecting the antenna layer and the transceiver circuit layer. An isolation layer through-hole is provided within the isolation layer, and a signal transmission line is disposed within the isolation layer through-hole. The two ends of the signal transmission line are respectively connected to the antenna on the antenna layer and the transceiver circuit on the transceiver circuit layer. This reduces the size of the radio frequency transceiver module while also reducing radio frequency attenuation and interference between the antenna and the transceiver.

Description

Technical Field

[0001] This utility model relates to the field of antennas, and in particular to a novel radio frequency transceiver module. Background Technology

[0002] Existing RF transceiver modules generally consist of two parts: an antenna and a transceiver. The antenna and transceiver are designed independently according to actual needs and are divided into two circuit modules. They are generally connected by RF coaxial cable soldering or by using RF connectors.

[0003] The advantage of designing the RF antenna and transceiver independently is that there is no cross-influence between the antenna and receiver, and the technology is easy to implement. The disadvantage is that, because the two modules are designed separately, whether connected via RF coaxial cable soldering or RF connectors, the RF lines, solder points, and RF connectors will introduce certain interference and attenuation. This interference and attenuation are discrete and require complex methods to eliminate and compensate for, increasing the complexity of subsequent overall system production. Furthermore, since the system consists of three independent parts—antenna, transceiver, and RF connector—it occupies a large space, posing an obstacle to the design of products requiring miniaturization and integration. Utility Model Content

[0004] The main purpose of this utility model is to provide a new type of RF transceiver module that integrates antenna and RF transceiver functions, effectively reduces RF attenuation and interference between the antenna and transceiver, improves the consistency of module mass production, and reduces the size of the RF transceiver module, which is conducive to the integration and miniaturization of the whole machine.

[0005] This utility model proposes a novel radio frequency transceiver module, including a module body, the module body including an antenna layer, a transceiver circuit layer, and an isolation layer disposed between the antenna layer and the transceiver circuit layer for isolating and connecting the antenna layer and the transceiver circuit layer.

[0006] The isolation layer is provided with an isolation layer through hole, and the signal transmission line is arranged in the isolation layer through hole. The two ends of the signal transmission line are respectively connected to the antenna on the antenna layer and the transceiver circuit on the transceiver circuit layer. This reduces the size of the RF transceiver module while also reducing RF attenuation and interference between the antenna and the transceiver.

[0007] Preferably, the antenna layer consists of at least one circuit board.

[0008] Preferably, there are two antennas, and an antenna layer through hole is provided in the middle of the antenna layer. The two antennas are mirror images of each other on both sides of the antenna layer through hole on the outside of the antenna layer.

[0009] Preferably, the isolation layer is composed of at least one circuit board, and an isolation layer through-hole is provided in the middle of the isolation layer.

[0010] Preferably, the transceiver circuit layer consists of at least one circuit board, and the transceiver circuit is disposed on the outside of the transceiver circuit.

[0011] Preferably, the system further includes a dielectric layer disposed between the antenna layer and the transceiver circuit layer. By providing the dielectric layer, mutual interference between the antenna and the transceiver circuit can be further reduced.

[0012] Preferably, a transceiver circuit layer through-hole is provided in the middle of the transceiver circuit layer.

[0013] The beneficial effects of this novel radio frequency transceiver module are as follows:

[0014] 1. By integrating the antenna and transceiver circuitry into the same structure, the size of the RF transceiver module can be effectively reduced.

[0015] 2. By setting an isolation layer between the antenna layer and the transceiver circuit layer, the radio frequency attenuation and interference between the antenna and the transceiver can be reduced.

[0016] 3. By setting through holes in the isolation layer and installing signal transmission lines within these through holes to connect the antenna and transceiver circuits, batch-related problems such as inconsistent line lengths and different numbers of solder joints caused by external line connections can be eliminated, thereby improving product yield and reducing errors.
