Description
Technical field
The utility model relates to electronic communication technology field, particularly relates to a kind of low-loss high stability height intermodulation double frequency 4G mixer.
Background technology
Wireless communication technology is through development for many years, enter the 3G epoch from the GSM epoch, and future more advanced 4G network had can be practical technology, also pilot is had at home, 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 the radiation transformed space of its institute's foundation and frequency resonance space is that electrolyte constant is close to 1, the free air that loss is minimum.Opening up the solution electric constant of various different size and controlled, and separating the lower new material replacement free air of matter loss, is realize antenna and filter complanation, microminiaturization and intelligentized Major Technology.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of low-loss high stability height intermodulation double frequency 4G mixer.
The utility model is achieved through the following technical solutions:
A kind of low-loss high stability height intermodulation double frequency 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, silver coated at the inwall of cavity, in inside cavity, band stray signal controlling element and multiple 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.
The utility model has the advantages that: the utility model is mainly used in communication system transmit-receive signal filtering device, can realize will the GSM/DCS/TDA/TDF of extensive use and LTE system signal simultaneously, not only can work as the use of single filtration module but also mixer use can be worked as, 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 DEG C, low-temperature working environment can reach-40 DEG C, 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 special defeated unobstructed, the plurality of advantages such as convenient for installation and maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
