The final goal for mm-w RF <strong>module</strong><br />
- 3 dimension<strong>all</strong>y integrate <strong>all</strong> circuits of RF front-end system into<br />
a single system-in-package. Using GND vias and planes, MMICs and<br />
passive circuits can be vertic<strong>all</strong>y deployed.<br />
Resonance and isolation<br />
- These GND structures can generate parasitic resonance modes<br />
that degrade integrated devices and the RF system.<br />
