Abstract
The invention discloses a low-loss, high-stability and high-intermodulation double-frequency 4G combiner. The combiner comprises a cavity and a cover plate, wherein an antenna port N-type connector is installed on the left side of the cavity, a GSM/DCS port N-type connector and a TDA/TDF/LTE port N-type connector are installed on the right side of the cavity, the inner wall of the cavity is plated with a silver layer, an out-of-band spurious signal control element and a plurality of high-power tuning capacitors are installed in the cavity, and the antenna port N-type connector, the GSM/DCS port N-type connector and the TDA/TDF/LTE port N-type connector are connected with the high-power tuning capacitors in the cavity through input transmission lines and output transmission lines. The low-loss, high-stability and high-intermodulation double-frequency 4G combiner has the advantages of being low in loss, high in intermodulation and power capacity, small in external dimension, beautiful in design, smooth in signal transmission, convenient to install and maintain and the like.
Description
Technical field
The present invention relates to electronic communication technology field, relate in particular to the high intermodulation double frequency of a kind of low-loss high stability 4G mixer.
Background technology
Wireless communication technology is through development for many years, enter the 3G epoch from the GSM epoch, and following more advanced 4G network had can be practical technology, also there is at home pilot, existing all kinds of antenna and transceiver input port be not low-loss, high intermodulation, selectivity mixer all still adopts irradiation structure and the multi-cavity resonance structure of solid type, bulky, complex structure, processing difficulties, become the major obstacle of wireless communications products microminiaturization: its main cause is that radiation transformed space and the frequency resonance space of its institute's foundation is that electrolyte constant is close to 1, the free air of loss minimum.Opening up the solution electric constant of various different sizes and controlled, and separating the lower new material replacement free air of matter loss, is to realize antenna and filter complanation, microminiaturization and intelligentized Major Technology.
Summary of the invention
The object of the invention is exactly in order to make up the defect of prior art, and the high intermodulation double frequency of a kind of low-loss high stability 4G mixer is provided.
The present invention is achieved by the following technical solutions:
The high intermodulation double frequency of a kind of low-loss high stability 4G mixer, include cavity and cover plate, in the left side of cavity, antenna port N Connector is installed, GSM/DCS port N Connector and TDA/TDF/LTE port N Connector are installed on the right side of cavity, inwall at cavity is silver coated, in inside cavity, band stray signal controlling element and a plurality of high-power tuning capacitance are installed, described antenna port N Connector, GSM/DCS port N Connector is connected with the high-power tuning capacitance of inside cavity by input and output transmission line with TDA/TDF/LTE port N Connector.
The material of described cavity is aluminium; Described high-power tuning capacitance material is Yi Chetie; The material of described band stray signal controlling element is copper, and electroplate.
The silver coating thickness of described cavity inner wall is CU3/Ag8.
Advantage of the present invention is: the present invention is mainly used in communication system transmit-receive signal filtering device, can realize simultaneously will extensive use GSM/DCS/TDA/TDF and LTE system signal, not only can work as single filtration module use but also can work as mixer and use, high intermodulation low-loss dual-frequency channel merger weatherability, inner employing high power resonant vibration electric capacity also adopts warm general effect, material is that easy car iron high-temperature work environment can reach 85 ℃, low-temperature working environment can reach-40 ℃, average power is that 53dBm peak power can reach 59dBm, mainly there is loss little, high intermodulation, power capacity is high, overall dimensions are little, be designed beautifully, signal is specially defeated unobstructed, the plurality of advantages such as convenient for installation and maintenance.
