Abstract

The embodiment of the invention provides a circuit board assembly. The circuit board assembly includes: a substrate, which is provided with a first port, a second port, a third port, a fourth port, a fifth port and a sixth port; a first diplexer which is arranged on the substrate and is provided with a first uplink port, a first downlink port and a first common port, wherein the first uplink port is connected with the first port, the first downlink port is connected with the second port, and the first common port is connected with the third port; and a second diplexer which is arranged on the substrate and is provided with a second uplink port, a second downlink port and a second common port, wherein the second uplink port is connected with the fourth port, the second downlink port is connected with the fifth port, and the second common port is connected with the sixth port.

Description

technical field [0001] The invention relates to the communication field, in particular to a circuit board assembly and electronic equipment. Background technique [0002] A traditional quadruplexer generally includes two duplexers. Taking B1 and B3 quadruplexers as an example, the antenna end (ANT port) is the common part of B1 and B3, carrying two radio frequency signals, which is actually combined in the middle based on the two duplexers of B1 and B3 The output reaches the function of four functions. [0003] Generally, the insertion loss of the above-mentioned traditional quadruplexer is higher than that of the single duplexer by more than 0.6db. [0004] In order to be compatible with CA (Carrier Aggregation, Carrier Aggregation) and non-CA radio frequency solutions, the traditional method is to be compatible with quadruplexers and two duplexers. Quadruplexers are used to support CA and non-CA. Diplexer. However, placing three devices in a PCB (Printed Circuit Board,...
