The MAX2027 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setup section for proper device evaluation. Table 2 lists
the attenuation setting vs. gain-control bits.
• DC supply capable of delivering 5.25V and 100mA of
• HP 8648 (or equivalent) signal source
• HP 8561E (or equivalent) spectrum analyzer capable
• Two digital multimeters (DMMs) to monitor V
• HP8753D (or equivalent) network analyzer to measure
• Lowpass filters to attenuate harmonic output of signal
This section provides a step-by-step guide to testing
the basic functionality of the EV kit. As a general pre-
caution to prevent damaging the outputs by driving
high-VSWR loads, do not turn on DC power or RF
signal generators until all connections are made.
Connect the header pins for B4–B0 to GND for maxi-
mum gain (15dB, typ). See Table 2 for other gain set-
ting configurations. To set a logic high on B4–B0, leave
the respective header pin unconnected as on-board
resistors pull up the logic to +5V. To control B4–B0
using external logic (voltage limits per data sheet),
ensure that +5V is applied to the chip. Failure to do so
can cause the on-chip ESD diodes to draw significant
current and may damage the part.
