1k Ω to avoid loading the RF input signal. There is an
internal resistor to GND of approximately 50k Ω . If the
control source high voltage is greater than 2.8V, calcu-

only sees a maximum of 2.7V, which is within specifica-

control device with a logic-high greater than 2.8V.

terns (footprints), go to www.maxim-ic.com/packages .
Note that a “+”, “#”, or “-” in the package code indi-
cates RoHS status only. Package drawings may show a
different suffix character, but the drawing pertains to
the package regardless of RoHS status.
The device is not particularly sensitive to the layout
since it only needs 3dBm for maximum output voltage.
However, there are two areas that need attention: the
GND pins and the supply bypassing. Connect the GND
pins to the PCB ground with a ground via as close as
possible, and bypass V CC to ground with a capacitor
