HMC960LP4E differential output impedance is 400 Ohm. With the help of two 174 Ohm serial resistances and a 140 Ohm shunt resistance ,it connected to the transformer of 2:1 resistance ratio. As a result, the 50 Ohm impedance of other side was mathed with it. That's what an expert has taught me in the forum. I still wonder that if I can delete the network of 174 Ohm and 140 Ohm resistances. And choose transformer of impedance ratio 8:1, to transform output impedance 400 Ohm into 50Ohm directly. Is it OK? I have reqused the help of the expert for many times, but has no response. Can You Help Me?
