We can see 1.5k ohms resistor on the input pin and the output pin of the functional diagram of the datasheet of HMC7357LP5GE. What is purpose of the resistor? Is it for matching to 50 ohms?
- These high resistors at input and output are for ESD protection only not for matching.
- I am curious why you are interested in these values when they are part of chip itself therefore you do not have external option for making changes?
Could you please advise me about the 1.5k ohms registor on the input pin and the output pin?
Thank you for your reply. It's our customer's question.
The resisters are shown on Functional Diagram and Pin Descriptions in the datasheet. But there is no information about the resistors. We are not sure the purpose of the resisters. So I posted this.
Thanks & regards
