hello all...
this is my first post and i'm new to RF design. hope to learn here. i assume something similar to this topic has been discussed but i would like to ask/verify some specific questions.
i need to match 75 Ohm source to very small load from 50 MHz to 1 GHz with discrete elements. can this be achieved by lumped LC matching networks? the load to match is approx 3-j*.088.
there are two concerns here: the S11 should ideally be -15 dB throughout the bandwidth but can degrade at higher frequency a little. the second concern is that the discrete elements need to be of reasonable size because i'd like to have on-chip matching if possible.
anybody has ideas how can this be done? is it possible? i tried a low-pass LC two section network but didn't get the intended results. do i need more sections? is there some other topology that would be better. thanks
