Frequency of Operation

The circuit board used in the final application

should use RF circuit design techniques. Signal

lines should have 50 ohm impedance while the

package ground leads and exposed ground paddle

should be connected directly to the ground plane

similar to that shown below. A sufficient number

of via holes should be used to connect the top
