Abstract
The utility model relates to a GSM and DCS signal mixer for mixing GSM signals and DCS signals into signals in one path and taking a 20dB signal from an antenna port for monitoring, which belongs to a short-wave communication device. The GSM and DCS signal mixer comprises a shell with integral structure; the inner cavity of the shell is partitioned into a GSM cavity, a DCS cavity and a coupler cavity, wherein a public space communicating with the GSM cavity and the DCS cavity is arranged between the GSM cavity and the DCS cavity; the coupler cavity is internally provided with a main signal wire and a coupling signal wire, one end of the main signal wire extends into the public space between the GSM cavity and the DCS cavity, and the other end of the main signal wire is used as an ANT port for leading out a monitoring signal of a mixing signal. The utility model can achieve the purpose that the ANT port monitors the 20dB signal from a GSM channel and a DCS channel simultaneously and has favorable signal mixing effect.
Description
Technical field
The utility model belongs to microwave communication device, relate to a kind of be used for GSM and DCS two paths of signals synthetic one the tunnel, and the GSM and the DCS signal combiner of monitoring from the signal of antenna opening taking-up-20dB.
Background technology
In the prior art, the road of closing for two paths of signals, traditional method all is by introducing a probe in required port, taking out institute's energy requirement by the size that changes the probe insertion portion monitors, and for the road of closing of GSM signal and DCS signal, only can't reach two paths of signals with a probe in the so wide frequency range of 890-1880 all is-20dB, thereby is difficult to reach the purpose that GSM signal and DCS signal are monitored simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of can be with the GSM and the DCS signal combiner of GSM and DCS signal synthetic a tunnel, make it can finish the purpose that GSM signal and DCS signal are monitored simultaneously preferably.
GSM of the present utility model and DCS signal combiner include an integrally-built housing, the inner chamber of housing is separated into a GSM cavity, a DCS cavity and a coupler cavity, public space of linking up GSM cavity and DCS cavity of tool between described GSM cavity and the DCS cavity; Be provided with main signal line and coupling signal wire in the described coupler cavity, an end of main signal line stretches into the public space between said GSM cavity and the DCS cavity, and the other end of main signal line is as drawing the ANT end that closes road signal monitoring signal.
The utility model can reach the purpose that the ANT mouth is monitored the signal of GSM and DCS two passage taking-up-20dB simultaneously, and it is effective to close the road.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, GSM of the present utility model and DCS signal combiner are that the housing 1 with an integral body is divided into a GSM cavity 2, a DCS cavity 3 and a coupler cavity 4, the public space 5 of two cavitys of tool between GSM cavity and the DCS cavity; Coupler chamber 4 bodies are the wide-band coupler cavity of one-20dB, be provided with main signal line 6 and coupling signal wire 7 in it, one end of main signal line stretches into the public space between said GSM cavity and the DCS cavity, and the other end of main signal line is as drawing the ANT end 8 that closes the road monitor signal.
