• All capacitors block DC, but the selection of a capacitor for a specific application is often a time-consuming process. One option is iterative testing of different capacitors and measuring the performance. Alternatively, one can speed the selection by using a capacitor capable of blocking across a wide frequency range. However, while a shorter path, this could be a costly solution

The models for MIM capacitors in some literature put the inductor due to the coplanar line nature of the DC-Block in front of the shunt capacitors, i.e. not inside the central branch, with series resistor and capacitor at one place. This is done in order to take into account the distribution effect along the two capacitor electrodes. So here the total inductor was
