Description

GSM/TDA/TDB/TDC four frequency combiners

[technical field]

The utility model relates to mixer, relates in particular to a kind of GSM/TDA/TDB/TDC four frequency combiners.

[background technology]

China's existing mobile communication network has entered the 3G epoch, GSM900/DCS1800 except original China Mobile, the GSM900/DCS1800 of CHINAUNICOM and CDMA800, the PHS of China Telecom, Netcom, WLAN, Digital Clustering and other communication systems have increased WCDMA, CDMA2000, TD-SCDMA 3G system again.The outdoor location network signal can cover by base station separately, and indoor signal can solve by traditional indoor covering system.It is more and more outstanding that yet each operator builds the problems such as repeated construction that covering system brought of oneself respectively.

[summary of the invention]

The technical problems to be solved in the utility model provide a kind of the communication signal of the GSM/TDA/TDB/TDC of different frequency range can be merged and unifies send, one group of signal that maybe will receive is shunted to four frequency combiners of GSM/TDA/TDB/TDC four road signals.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of GSM/TDA/TDB/TDC four frequency combiners, comprise casing, described casing comprises cavity, cover plate, input port and output port, rear side at casing is provided with input port, the front side of casing is provided with output port, input port has four, is respectively the TDC port that frequency range is the GSM port of 885-954MHz, TDA port that frequency range is 1880-1920MHz, frequency range is 2010-2025MHz TDB port and frequency range are 2300-2400MHz; Described cavity is separated into four resonance group chambeies that operating frequency range is different.

Further be, the TDC resonant cavity that TDB resonant cavity that the TDA resonant cavity that the GSM resonant cavity that described four groups of resonant cavitys are respectively 885-954MHz, frequency range are 1880-1920MHz, frequency range are 2010-2025MHz and frequency range are 2300-2400MHz, one end of every group of resonant cavity is connected with corresponding input port, and the other end of resonant cavity is connected with output port by public port.

Further be that described four groups of resonant cavitys are made up of several single chambeies respectively.

The beneficial effects of the utility model are, the communication signal of GSM, TDA, TDB and TDC are merged and unifies send, and one group of signal that maybe will receive is shunted to GSM, TDA, TDB and TDC four road signals, simplifies installation, dependable performance.
