Embodiment Construction

[0030] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0031] Such as figure 1 , 2 As shown, a resistive-based ultra-wideband six-way power divider of the present invention includes: thin film resistors R1, R2, R3, R4, R5, R6, R7, matching microstrip lines TL1, TL2, TL3, TL4, TL5, TL6 , TL7, connection plate D;

[0032] The input signal enters the connection pad D through the microstrip line TL1 and the thin film resistor R1 in sequence;

[0033] The connection board D divides the input signal into six channels and outputs them to the branches composed of R2, TL2, R3, TL3, R4, TL4, R5, TL5, R6, TL6, R7, and TL7 (R2, TL2 form a branch, and R3 , TL3 form a branch, and so on, R7, TL7 form a branch), and then output by each branch;

[0034] For microwave circuits, in order to meet the matching requirements of each port, the ideal mode is to see from any port of the circuit, and the characteristic impedance is Z 0 . In o...

Abstract

The present invention is a resistive-based ultra-wideband six-way power divider, which includes thin film resistors, matching microstrip lines, and connecting plates; input signals enter the connecting plates through microstrip lines and thin film resistors in turn; the connecting plates divide the input signals into six channels They are respectively output to six branches, and then output by each branch; the connection plate is a semicircular connection plate. The invention reasonably selects the resistance value, and designs a special multi-channel interconnection plate, and simultaneously realizes the ultra-wideband of the six-way power divider from 0.1GHz to 8GHz and the miniaturization of 20mm×16mm, and has excellent performance and consistent amplitude in the whole frequency band Better than 2.1dB, the input standing wave is better than 1.8, the output standing wave of any port is better than 1.52, and the isolation is better than 14dB.

Description

technical field [0001] The invention is a resistance-based ultra-wideband six-way power divider, which belongs to the technical field of microwave circuits. Background technique [0002] The ultra-broadband power splitters known in public publications and public channels mainly include the following: multi-stage Wilkinson power splitters, branch line power splitters and some special power splitters. However, these power splitters are large in size and cannot meet the requirements of miniaturized whole machine integration (the size requirement is at least less than 20mm×60mm), and it is difficult to achieve a leap from 0.15GHz to 8GHz in terms of performance. [0003] (1) Wilkinson Power Splitter [0004] After investigation, the ultra-wideband power splitters learned from public publications and public channels are mainly in the Wilkinson form. For example, Sun Changyou published "Development of Broadband Multi-section Wilkinson Power Divider" in "Electronic Components and...
