Hi all

 

when i use hmc943 in K band (24G~24.25G). i want to do the impedance match for it to get better VSWR

 

i use the microstrip to match the chip. But the result is not satisfied.

 

1:The attachment is the dxf of the match microstrip. Can you give me some advice?

 

2:Firstly,i draw the layout of the microstrip in HFSS and  i simulate the microstrip lonely in HFSS , then i output 

the SNP file of the microstrip. Lastly, i input the SNP file of the microstrip into ADS and connect it to the SNP of HMC943A  . So i can get the result of the chip and microstrip. Does this method is correct?

 

Thanks

look forward for your reply.
