hi,
I am designing a 90 degree hybrid on MMIC in ADS. My design is complete with no Transmission lines.
I didn't do any design till now with matching networks in ADS.
I think the next step is replacing all the lines with lamda/2 Trans lines and then after check the input impedance for mismatch and accordingly i should match it to 50ohms.Now after this what should i optimize if it doesn't give required specs.
One more question should i have to check stability factor(K) of a passive device for a good operation in 14.125 GHz(750 MHz). My friend told me that since there is no loops there is no need to check for stability is it right?
please help me.
thanks.
