limiting amp

Hey everyone,

I’ve been working on a high-speed signal project and I’m using the ASNT5131-KMC limiting amplifier . It’s really cool, it works from DC up to 28 GHz, and can adjust output amplitude, which gives me more control over signal strength.

Right now, I’m feeding in a differential high-speed signal and using the tuning ports on the chip to control how “big” the output swing is. I’m running it on ±5 V.

My main tests so far are:

Seeing how stable the output amplitude is when I tweak the tuning voltage

Measuring how much jitter the chip adds under different signal conditions

Checking thermal behavior under continuous use

Has anyone here used the ASNT5131-KMC or a similar SiGe limiting amplifier in their designs? Would love to get your take on its tuning behavior, noise performance, or any layout tricks that helped you.

Thanks in advance!
