The MAX2659 EV kit is fully assembled and tested.
Follow the steps below for a step-by-step guide to
operating the EV kit and testing the device functions.
Connect pin 1 to pin 2 of JP1 to enable the device.
Caution: Do not turn on the DC power or RF signal
generators until all connections are completed.
1) Connect a DC supply set to +2.85V to the V

A good printed-circuit board (PCB) is an essential part
of RF circuit design. The EV kit PCB can serve as a
guide for laying out a board using the MAX2659. Use
controlled impedance lines on all high-frequency inputs
and outputs. Bypass V
located close to the device. For long V
be necessary to add decoupling capacitors. Locate
these additional capacitors farther away from the
device package. This minimizes supply coupling.
Proper grounding of the GND pins is essential. Connect
the GND pins to the ground plane either directly, or
through vias, or both.
