Specifications of MAX2741EVKIT

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The MAX2741 EV kit simplifies evaluation of the MAX2741
GPS RF receiver front-end IC. It enables testing of the
device’s RF performance and requires no additional sup-
port circuitry. The EV kit’s signal inputs and outputs use
SMA connectors to facilitate the connection of RF test
equipment. In this section, detailed descriptions of the EV
kit board as well as the control interface/software are
given to facilitate better evaluation of the IC.
The MAX2741 EV kit has one RF input port, two IF output
ports, one IF input port, one reference clock input port,
and a GPS IF output port:

Important Notice: The EV kit board provides all neces-
sary components to test the entire tuner as one receiver
(RF input to the 2nd IF analog output) or to indepen-
dently test the 1st stage (RF input to 1st IF output) and
the 2nd stage (the 2nd IF input to the 2nd IF output). All
the required passive components are provided and
installed on the board.
To test the entire tuner as one receiver, the user must
disconnect the connections to the 1st IF output SMA
and the 1st IF input SMA by removing C35, C36, C37,
and C38.
To test the 1st stage and the 2nd stage independently,
the user must disconnect the connections to the pas-
sive, interstage IF filter by removing R12, C39, C40,
C41, C42, C44.
There are eight jumpers on the MAX2741 EV kit. See
Table 1.
