Hello
I was designing 10W 3 Ghz PA using cgh40010 in ADS, for stability i used at the gate a parallel RC, where R = 10 ohms, C = 4.7pF, I initially relied on small signal mu factor, and it was good.
for layout cosimulation results were fine, except that if I simulate mu stability factor using Large signal S parameters i get a dip below ONE only at my operating band ...

Hi everyone,I would like to share some practical experience on PCB manufacturing for high‑speed circuit projects.Many small‑batch projects face challenges in impedance control and material selection. For prototype runs, careful stack‑up review can help avoid rework later.What factors do you usually prioritize for your prototype PCB orders? Looking forward to your ideas.

The 100 -150A High-Performance and Long-Endurance Electronic Speed Controller (ESC) is a versatile, high-efficiency motor control platform designed to deliver reliable power management, precise motor control, and extended operating endurance across a wide range of electric-powered applications.

The project focuses on developing a robust ESC capable of handlin...

When I calibrate i see that the ECAL did a bad job . Is there a manual or method on how to fix the ecal calibration profile inside the PNA? Thanks.

Hello ,I am calibrating the vna cables as shown below. the vna cables are bended .
so when I connect the DUT , by definition the cables are not in the same position where they were calibrated by. so from the start my calibration breaks.
What strategy to use regarding ecal DUT position so the calibration will be kept opyimal.
Thanks.
