Title: Substrate coupling
Post by Ricky Chen on Apr 5^th, 2012, 8:01pm

Dear all,

I have used Static Divider for Multiphase generation and to drive my passive Mixers. They are close to each other. I am worried about the noise (delta I current) coupling to other parts of my circuits. It operates at 4 GHz.
Can anybody tell what can be done so that the LO part can't affect other part of my circuits. I have separate VDD and GND for the LO part.
