Layout Considerations
The EV kit serves as a guide for PC board layout. Keep
RF signal lines as short as possible to minimize losses
and radiation. Use controlled impedance on all high-
frequency traces. For proper operation of the TQFN
package, the exposed paddle must be soldered evenly
to the board ’s ground plane. Use abundant vias
beneath the exposed paddle for maximum heat dissi-
pation. Use abundant ground vias between RF traces
to minimize undesired coupling. Bypass each V CC pin
to ground with a 100pF capacitor placed as close to
the pin as possible.
In addition, the ground returns for the VCO, VTUNE,
and charge pump require special layout consideration.
R21
The VCOBYP capacitor (C37) and the VCCVCO bypass
capacitor (C19) ground returns must be routed back to
the GNDVCO pin and then connected to the overall
ground plane at that point (GNDVCO). All loop filter
component grounds (C27 –C30) and the VCCCP
bypass capacitor (C17) ground must all be routed
together back to the GNDCP pin. GNDTUNE must also
be routed back to the GNDCP pin along with all other
grounds from the PLL loop filter. The GNDCP pin must
then be connected to the overall ground plane. Figure
4 shows a schematic drawing of the required layout
connections. Refer to the MAX2160 evaluation kit for a
recommended board layout.
