MAX1479 Evaluation Kit
General Description
The MAX1479 evaluation kit (EV kit) allows for a detailed
evaluation of the MAX1479 ASK/FSK transmitter. It
enables testing of the device’s RF performance and
requires no additional support circuitry. The RF output
uses a 50 ? matching network and an SMA connector for
convenient connection to test equipment. A reverse polar-
ity SMA is also included to connect to a 1/4 wave whip
antenna. The EV kit can also directly interface to the
user’s embedded design for easy data encoding.
The MAX1479EV kit comes in two versions: a 315MHz
version and a 433.92MHz version. The passive compo-
nents are optimized for these frequencies. These compo-
nents can easily be changed to work at RF frequencies
from 300MHz to 450MHz.
For easy implementation into the customer’s design, the
MAX1479EV kit also features a proven PC board layout,
which can be easily duplicated for quicker time-to-
