Thank you for the support Kai!
Hello Tarun,
Here are some resources for PCB layout considerations for high speed design:
High Speed PCB Layout Techniques (This one is a very handy guide) '
High Speed Layout Guidelines (digital and analog)

Hello Nacho,
Thank you for the additional information. Ah, I see now, thank you for the explanation on MPPCs!
The PCB is very organized; these are minor suggestions, but some components could be placed closer to the pins of the amplifiers. Also, we…
Hello Andrea,
Thank you for providing the additional clarity.
I have a couple questions:
1) R5 looks like a resistor on the input signal path. Is the trace going to the left of R5 a connector, an IC, a test-point? Does this signal stay on the top…
Hi,
Are you looking for the EVM layout files?
Or are you looking for something like this?

The application section and forward area of the datasheet should also be read. It has lots of guidance on building…
Hi Sally,
A TINA model is a SPICE based model we provide with some of our parts.
When there is a long transmission line, longer than a quarter wavelength, there are reflections on the line. VGA transmission lines are typically impedance matched at…
I confirm this block diagram.
1. Yes
2.This depends on the Pi attenuator. At the BMC (BNC?) input, you must have 75 ohms to ground. If your Pi attenuator has an input of 75 ohms, this resistor is not needed.
3. If you keep layout tight, you need…
Hi Shimizu,
To answer your questions about the effect of Counter-measure 1, and 2:
Counter-measure 1 (adding 10pF to ground on non-inverting input of the 2nd stage): I've seen this before that the input of a high speed amplifier can be susceptible…
Hello Tansel,
The UAF42 topology does not accommodate differential operation. I suggest using a multiple-feedback (MFB) active filter which lends itself nicely to a differential input, or fully differential filter. I wrote an article for TI's AAJ some…
Hi Lee Johnny,
The attached document, ( Chapter 3 : Basic Memory management) gives clear explanation about using the memory and changing the memory locations in the linker command file. Please have a look and revert if there are any further questions…
