Hi all,
I am working on design and prototype prudustion of small signal RF amplifiers working between 0.8Ghz to 2GHz. I have chosen to use SBB-5089 MMIC amplifer from Sirenza MD and implemented two circuits using these MMICs. Although I have used the same passive elements in both circuits, the experimental results are different as in the attached document. One of the circuit is good, it has flat chracteristics but the other one has a lot of ripple. Can anyone tell me which can cause this ripple?
Thanks
