How to design the matching network of ADL5324 and ADL5523

Hello!

I am trying to design the tuning the ADL5324 and ADL5523, here is my problem.

Question 1. The Power Amplifier ADL5324 Evaluation Board's default frequency is 2110 MHz - 2170 MHz. But I want it to work at frequency of 3100 MHz - 3400 MHz. Is it possible to simulate the matching network in ADS?  Like the picture shows.

The simulation result seems different from the datasheet. Or maybe I could only modify the component on the board directly?

Question 2. I also want the LNA ADL5523 evaluation board to work at frequency of 3100 MHz to 3400 MHz. As it is a LNA, we want to tune it for optimal noise figure.  But it seems impossible to simulate it in ADS because I looked the SNP file and there is no data about Noise Figure, Fmin, GAMMA OPT. Could anyone tell me how to design the matching network?

Any advice would be apprciate.

Thank you!

  • Hello, Jim

    Thank you for your suggestion last time.

    Now I am trying to implement ADL5324 and ADL5523 on my own board. As I have gotten some useful values of

    the matching network from the evaluation board, I want to use the same substrate as the evaluation board. From

    the datasheet, I have known the substrate is a four-layer FR4 material. But I don´t know the the thickness of each

    layer and the copper. Could you give me some detailed information about the substrate. Thank you very much.
