The different frequency band combiner refers to the signal power synthesis of two different frequency bands. For example, RF Combiner CDMA and GSM power synthesis; CDMA/GSM and DCS power synthesis. Due to the large frequency separation of the two signals, RF Combiner the two frequency signals can be synthesized by the frequency selection method of the resonant cavity. RF Combiner Its advantages are small insertion loss and high out-of-band suppression. The out-of-band suppression index is one of the most important indicators of the combiner. One, if the out-of-band suppression is not enough,RF Combiner it will cause mutual interference between GSM and CDMA.
The combiner is divided into the same frequency combiner and different frequency combiner. The same frequency combiner is a 3dB bridge. The different frequency combiner is to combine N signals of different frequencies into one output microwave device, and it is widely used in Indoor coverage, WLAN, RF Combiner cell coverage, and other systems.
As the manufacturer of RF passive components, Jingxin can specially design rf combiner , hybrid coupler , as your solution, so hopefully we can support you any time.
