impedance, they are more susceptible to component
parasitics. It is often good practice to relieve the
ground plane directly underneath large components to
reduce associated shunt-C parasitics.
The EV kit’s PC board can serve as a guide for laying
out a board using the MAX2045/MAX2046/MAX2047.
Keep RF signal lines as short as possible to minimize
losses and radiation. Always use controlled-impedance
lines on all high-frequency inputs and outputs and use
low-inductance connections to ground on all GND pins.
At all differential ports, keep the differential lines togeth-

er and of the same length to ensure signal balance. The
PC board layout should provide a large ground pad
under the device for proper RF grounding and thermal
performance. This pad should be connected to the
ground plane of the board by using multiple vias. To
minimize inductance, route the ground pins of the
device to the large ground pad. Solder the exposed pad
on the bottom of the device package to the PC board
exposed pad (refer to the MAX2045/MAX2046/
MAX2047 data sheet).
The MAX2045/MAX2046/MAX2047 EV kits can be used
as a reference for board layout. Gerber files are avail-
able upon request at www.maxim-ic.com.
