A properly designed PCB is an essential part of any
RF/microwave circuit. Keep RF signal lines as short as
possible to reduce losses, radiation, and inductance.
For the best performance, route the ground pin traces
directly to the exposed pad under the package. The PCB
exposed pad MUST be connected to the ground plane
of the PCB. It is suggested that multiple vias be used to
connect this pad to the lower-level ground planes. This
method provides a good RF/thermal conduction path for
the device. Solder the exposed pad on the bottom of the
device package to the PCB.

DESCRIPTION
DESCRIPTION
Proper voltage-supply bypassing is essential for high-
frequency circuit stability. Bypass each V
capacitors shown in the Typical Application Circuit and
see Tables 1 and 2.
The exposed pad (EP) of the MAX2042’s 20-pin thin QFN
package provides a low thermal-resistance path to the
die. It is important that the PCB on which the MAX2042
is mounted be designed to conduct heat from the EP. In
addition, provide the EP with a low-inductance path to
electrical ground. The EP MUST be soldered to a ground
plane on the PCB, either directly or through an array of
plated via holes.
