Thanks Abhishekabs for kindly help, but IL(coupled coef)of 2in-2out couplers I need have to be below 3.5dB from 800M to 2.2G, directional couplers are unlikely to achieve I guess, maybe branchline structrue is a way but I dont know.
thanks Abhishekabs. But my boss expected to make a combiner design with pcb board like microstrip or anything else related to pcb. as Kspalla said, suspended air stripline may be applied to design, but how do?
Are suspended air strip line you meationed same trace on both side of pcb board with same air space room away from box? Do you have concrete design guide?
Kspalla,
the whole structure consist of 4 2-to-2 couplers realize function: any input(left side) signal flowed can get to arbitrary output port(right). In fact, question is how to design a boardband 2in-2out couplers? if this can be done, the total will be the combination of it.
Biff44,
Are you sure that stripline style can reach this function? other limitation is that it can stand power surge of at least 500W. Do you have any paper on using of stripline espcially on windband coupler application. thanks.
Total structure is:
function: windband signla at arbitrary...
Today boss give me a task, wideband couplers or hybrid couplers like branch line frequency ranged from 800MHz to 2.1GHz with less than 3.2dB of couple coefficient, my question is whether microstrip structure can realize? if not, how to get a start? I am lna designer and new to couplers, therefor...
if you are for RF layout , i think boardstation will be your best choose, because there are some ADS lib in boardstation, you can directly edit these lib used for RF design in BS, you maybe do a attempt.
Have anyone work in RF design and RF layout ？I knew that ADS tool have been used at RF design for get more accurate simulation，and this process import IFF format file into DA/BA from ADS schematic is same very importment ，but have anyone can finish it perfectly？If anyone got it，let us make a...
Can anyone tell me how to detect frequent to Automatically disabled in absence of carrier？When an input signal is detected, the cavity automatically tunes itself to the input frequency cross step motor.
