Parallel (shunt) inductor
As shown in Fig 151, the equivalent shunt inductor is grounded at one end (a grounded stub) through a via to the groundplane of the PCB or, as will be shown, it may also be RF grounded through a distributed equivalent capacitor to ground Step 1: Knowing the inductance required within the circuit, calculate the reactance of the shunt inductor, at the frequency of interest, by the common formula: XL = 2pfL Step 2: Use 100- microstrip (ZL = 100 ) for the substrate s dielectric in use Find the microstrip width required for this 100- value by either using one of the many

A Quick Example Design a Distributed Shunt Inductor (Fig 152) Goal: Create a distributed shunt inductor to replace a lumped part The frequency of operation is 58 GHz and the inductance required is 1 nH The substrate is FR-4 (Er = 46), with a thickness of 20 mils Solution: 1 Inductive reactance of a 1-nH capacitor is 36 2 The width of the distributed inductor s microstrip will be 7 mils 3 The length will be 64 mils (using ARCTAN)
Choke [Radio Frequency Choke (RFC)]
The distributed choke is RF grounded (a grounded stub) through a distributed, or lumped, capacitor (Fig 153), or by being directly grounded through the groundplane [Fig 154(a)] The width of a distributed choke is that of 100- microstrip for the substrate s dielectric in use (ZL = 100 : 100 is the impedance of the microstrip only, and not that of the equivalent choke) Find the microstrip width required for this 100- value by either using one of the many microstrip calculation programs available for free on the Web (such as HP s AppCad, AWR s TXLine, Daniel Swanson s MWTLC, or so on),
