Abstract
The utility model relates to a power splitter manufactured by use of a semi-lumped method. The power splitter mainly comprises an input port and an output port; an impedance transformer of each level adopts a structure that inductors are in series and capacitors are in parallel; every two shunt circuits are isolated by use of an isolating resistor. The impedance input and output by the isolating resistors is 50 ohms. The power splitter adopts a four-level impedance changing structure; air core inductors formed by winding lacquered wires are adopted as the inductors in series, and high Q valve microwave capacitors are adopted as the capacitors in parallel. The utility model has the advantages that the power splitter, which is manufactured by use of the semi-lumped method and has the structure, can effectively reduce the volume of devices and realize required indexes.
Description
Technical field
The utility model relates to the power splitter field, mainly is the power splitter that a kind of usefulness half lump method is made.
Background technology
In present communication system, the signal of broadcasting and cable TV need be inserted subway, so just need signal be carried out shunt with power divider.Need certain isolation between shunting sign, will use Wilkinson type power splitter so.If the mode of using traditional microstrip line to realize, because frequency is very low, volume will be very big so.
Summary of the invention
The utility model will solve above-mentioned existing shortcoming, the power splitter that provides a kind of usefulness half lump method to make.
The utility model solves the technical scheme that its technical problem adopts: the power splitter that this usefulness half lump method is made, mainly comprise input port and output port, the impedance transformer of each grade adopts inductance serial connection and electric capacity parallel-connection structure, isolates with isolation resistance between each shunt.
The impedance of described isolation resistance input and output all is 50 ohm.
Described this power splitter has adopted 4 grades impedance variation structure, the air core inductor that series inductance adopts the enamelled wire coiling to form, and shunt capacitance adopts the microwave capacitors of high Q value.
The effect that the utility model is useful is: the power splitter that uses a kind of half lump method to make, the power splitter of this structure can effectively reduce the volume of device, realizes the index that requires.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram;
Reference numeral: input port 1, output port 2, isolation resistance 3, inductance 4, electric capacity 5.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, three road power splitters with a kind of 80-220MHz are that example describes: the power splitter that this usefulness half lump method is made, mainly comprise an input port 1 and three output ports 2, the impedance transformer of each grade does not use the microstrip line of 1/4 wavelength and uses inductance 4 serial connection and electric capacity 5 parallel-connection structures instead, isolates with isolation resistance 3 between each shunt.The impedance of described isolation resistance 3 input and output all is 50 ohm.Because frequency band broad, therefore this power splitter has adopted 4 grades impedance variation structure, the air core inductor that series inductance adopts the coiling of 1mm enamelled wire to form, shunt capacitance adopts the microwave capacitors of high Q value, thereby the insertion loss that makes device is less than 0.5dB, and return loss is greater than 15dB, and the isolation of each delivery outlet is greater than 20dB, it is little to have satisfied volume preferably, the requirement that index is good.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
