planes. This method provides a good RF/thermal con-

duction path for the device. Solder the exposed pad on

the bottom of the device package to the PCB. The

MAX2016 Evaluation Kit can be used as a reference for

board layout. Gerber files are available upon request at

Power-Supply Bypassing

Proper voltage-supply bypassing is essential for high-

frequency circuit stability. Bypass each VCC pin with a

capacitor as close to the pin as possible (Typical

Application Circuit).

Exposed Pad RF/Thermal Considerations

The exposed paddle (EP) of the MAX2016’s 28-pin thin

QFN-EP package provides two functions. One is a low

thermal-resistance path to the die; the second is a low-

RF impedance ground connection. The EP MUST be

soldered to a ground plane on the PCB, either directly

or through an array of plated via holes (minimum of four

holes to provide ground integrity).
