Technical field
The present invention relates to a kind of non-directional broadband and do not wait branch/coupler, belong to microwave telecommunication devices technical field.
Background technology
" TAPCoupler " one word refer generally to three port passive microwave devices, be divided into two output channels for microwave carrier an input channel.
Known power coupler comprises: Lange coupler, branch line coupler, directional coupler, threeway coupler and other Wilkinson coupler.Directional coupler comprises single cross section, multi-section and conical design etc.
Equal or not etc. value is divided at output port input signal, in equal distribution situation, the power of every two output ports equals the half of input power, the ratio of power output, is called split ratio, and R is 1:1, one of them output port is standardized as 1, under unequal distribution condition, input signal is divided into two output ports, makes R value be greater than 1.
Unequal power divider results from broadband, distributed, the increase of the demands such as high power transmission system, in the application of more complicated system, as set up bidirectional passive distributed antenna system, the signal of the different frequency needed for sending and receiving, in this application, a main channel is distributed in whole building by coaxial wire from a base station or repeater, branch line is added at main coaxial cable, and provide signal to different floor, non-directional coupler is necessary, if every floor all accepts same power, in the allocation proportion of corresponding every floor adjustment coupler, typical distribution ratio is between 3dB (R is 1:1) and 30dB (R is 999:1).
To some difficulties that following application provides non-directional coupler relevant, as follows: first, in wider frequency range, be difficult to the coupling value providing maintenance one constant.Secondly, non-directional coupler input mouth is difficult to provide lower or close to the voltage standing wave ratio (VSWR) of minimum value 1, VSWR is the standing-wave ratio of transmission line peak to peak.As everyone knows, as: load, the input of coupler, line characteristic impedance, when coaxial cable feed signal is to coupler, when there is no reflected wave, so V
max=V
minor VSWR is 1, emphasis to keep low-voltage standing-wave ratio that the unmatched loss with equipment is minimized.In addition, non-directional coupler is difficult to process high power and passive low intermodulation (PIM), and is difficult to provide good line characteristic impedance in wideband frequency range.
