Specifications of MAX2510EVKIT-SO

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The following section provides instructions for operating
the EV kit as an IF transceiver. The RF ports (RXIN,
RXIN, TXOUT, and TXOUT) are matched to 50Ω at
240MHz, and the second IF is configured for 10.7MHz
operation. The EV kit and the MAX2510 can be config-
ured for operation at other frequencies (see the
Detailed Description section and the MAX2510 data
sheet).
This section lists the test equipment recommended for
verifying operation of the MAX2510. It is intended only
as a guide; some substitutions may be possible.

Test Equipment Required
This section provides step-by-step instructions for get-
ting the EV kit up and running in both Tx and Rx modes.
Perform the following steps to set up the EV kit in Tx
mode:
1) Make the DC connections: set the power supply to
2) Set the part in Tx mode by putting 3-pin jumper
3) The supply current should be near 30mA. If this is
4) Connect TXOUT to the spectrum analyzer using an
5) Connect the local oscillator (LO) signal source to
6) Set both channels of the baseband-signal genera-
3V, and connect it to the VCC and GND terminals
on the EV kit. Set one of the voltage sources to
1.4V, and connect it to VBIAS. Set the other voltage
source to 2V, and connect it to the gain-control ter-
minal (marked GC).

minator.
For differential operation, TXOUT and TXOUT can
be combined using a balun. Connect the balun’s
output to the spectrum analyzer. Set the spectrum

total span.

240MHz and the amplitude to -13dBm. You will see
a small amount of LO signal present at the center of
the spectrum-analyzer display.
tor to deliver sine waves at 500mVp-p at a fre-
quency of 100kHz. To achieve maximum sideband
suppression, be sure that there is a precise 90°
phase difference between these two sinusoidal
signals. Connect the first signal to the I input. You
will see a double sideband signal (DSB) on the
spectrum analyzer at 240MHz, with the lower side-
band at (240MHz - 100kHz) and the upper side-
band at (240MHz + 100kHz). Connect the other
signal to the Q input. If the phase difference is set
correctly, you will see a cancellation of the side-
bands. Which sideband is canceled depends on
which input leads the other in phase. Swapping
the I and Q connections at the board’s input sup-
presses one or the other sideband. Leave the part
set to transmit the upper sideband (USB) when fin-
ished. The rest of these instructions assume the
