APPLICATIONS INFORMATION

Evaluation PC Board

The evaluation PCB is very versatile and is intended to be

used across the entire useful frequency range of this device.

The PC board accommodates all SMT components on the

circuit side (see Circuit Side Component Placement View).

This evaluation board will be discussed and referenced in

this section.

Component Selection

The evaluation PC board is designed to accommodate

specific components, while also being versatile enough to

use components from various manufacturers. The circuit

side placement view is illustrated for the components

specified in the application circuit. The application circuit

schematic specifies particular components that were used to

achieve the results given and specified in the tables but

alternate components of the same Q and value should give

equivalent results.
