hi, what is the difference between HMC349 with HMC349A, and HMC472 with HMC472A? thanks.
thanks, Selcuk.
Are there any change about the internal structure, such as voltage control pins(V1 to V6) of HMC472A?
customer used HMC472 in his previous design, and in quiescent testing, the earth impedance is about 50Kohm, but for HMC472A, it is 1Mohm. could you please help check about this?
