and LO-to-IF isolation, use 10nH inductors (L3 and L6)
in place of the 0 Ω resistors. However, to ensure stable
operation, the mixer IF ports must be presented with
low common-mode load impedance. Contact the facto-
ry for details. Since approximately 100mA flows through
INDEXTM and INDEXTD, it is important to use low-DCR
wire-wound inductors.
Layout Considerations
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-con-
duction path for the device. Solder the exposed pad on
the bottom of the device package to the PCB. The

Power-Supply Bypassing
Proper voltage-supply bypassing is essential for high-

capacitor as close as possible to the pin ( Typical
Application Circuit).
Exposed Pad RF/Thermal Considerations
The exposed pad (EP) of the MAX9995’s 36-pin TQFN-
EP package provides a low thermal-resistance path to
the die. It is important that the PCB on which the
MAX9995 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.
