LAYOUT CONSIDERATIONS

The RF spiral inductor is electrically connected to the circuit by wire bonds. All wire bonds add parasitic inductance and

resistance, as shown in Figure 1.

It is important to note that setup variations might affect the performance of the component. Special care must be given to minimize

these effects by careful design of the component host circuit board. The following aspects should be considered:

• Bond wire length should be minimized. The bond wire added inductance can be roughly estimated at 0.75 nH per mm of

1.25 mil diameter gold wire.

• Any ground plane directly under the component will increase the parasitic shunt capacitance. This will cause self-resonance at

lower frequencies.

• The epoxy used to attach the component is the limiting factor in power handling. For applications that require high power

handling it is recommended to use high temperature epoxy and to ensure adequate heat sinking.
