Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a three-frequency two-port combiner.
Background
The combiner is generally used at the transmitting end, and functions to combine two or more radio frequency signals sent from different transmitters into one radio frequency device sent to the antenna, and meanwhile, avoid the mutual influence between the signals of all ports. The combiner typically has two or more input ports, with only one output port. Port isolation is a relatively important indicator for describing the capability of two paths of signals not to affect each other, and is generally required to be more than 20dB. The 3dB bridge combiner has two input ports and two output ports, and is commonly used to combine two wireless carrier frequencies and then feed the combined two wireless carrier frequencies into an antenna or a distribution system. If only one output port is used, the other output port needs to be connected with a 50W load, and the signal is in 3dB loss after being combined. Sometimes both output ports are used, no load is needed and no 3dB loss is present.
The signal mobile phone receives and sends signals to one antenna. In the GSM system, because the receiving and transmitting are not in the same time slot, the mobile phone can omit a duplexer for isolating the receiving and transmitting, and can combine the receiving and transmitting signals onto one antenna without mutual interference by using a simple receiving and transmitting combiner.
