Hi all,

 

Our customer will consider to design the programmable divider circuit, divide by 48, with HMC394 & HMC365.

Input signal : sine wave,  1536MHz

 

Following is questions,

1.What is the each input/output impeadance ? 50 ohm ?

 HMC394 :input ? ohm / output ? ohm

 HMC365 :input ? ohm / output ? ohm

 

2.About HMC365SG8E, Duty cicle 50 % of Input signal have to enaght ?

Does the input signal of HMC365 must be duty 50%?
If it is 50% or more or less (eg 30%, 70%), will the HMC365 work normally?

 

3.Following is work normally,  total divide by 48 ?

sine wave, 1536MHz input >>> HMC394LP4E (divide by 12) >>> AC coupling >>> HMC365SG8E (divide by 4) >>> output

or

sine wave, 1536MHz input >>> HMC365SG8E (divide by 4)>>> AC coupling >>> HMC394LP4E (divide by 12) >>> output

 

Best regards,

sss
