Hello,

I have a very simple question that I haven't found an answer to it anywhere online.

If I want to design a wideband filter—or any other circuit— that it have parallel components (like in the image below) as a electrical schematic. And I'm using lumped elements, how should I implement it in the layout for achieve good and wideband performance.

I.E like using ADS?

What I'm currently doing isn’t working at all.
maybe use Wilkinson divider but it make it too complicated.

Your schematic is a bandstop network. If you want to make a passband, try other ways to arrange C&L network:
* Put C & L in series.
* Or connect LC tank to ground.

As a general thing, select C & L values to accommodate the amount of current available.
L:C ratio governs steepness of your rolloff curve.

Greater C is associated with Low frequencies, lesser impedance.
XC=1/(2πfC)

Greater L is associated with Low Frequency, greater impedance.
XL=2πfL

Example, center frequency is 25 MHz or so:

Thank you very much,
I indeed can find different topology, but I wanna to apply the parallel topology, for learning how to make a high frequency microstrip parallels connections.
Using tee junction? Round junction? two Wilkinson's?
