MAX1472 Evaluation Kit
General Description
The MAX1472 evaluation kit (EV kit) allows for a
detailed evaluation of the MAX1472 ASK transmitter. It
enables testing of the device’s RF performance and
requires no additional support circuitry. The RF output
uses a 50Ω matching network and an SMA connector
for convenient connection to test equipment. A reverse-
polarity 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 MAX1472 EV kit comes in two versions: a 315MHz
version and a 433.92MHz version. The passive compo-
nents are optimized for these frequencies. These com-
ponents can easily be changed to work at RF frequen-
cies from 300MHz to 450MHz.
For easy implementation into the customer’s design, the
MAX1472 EV kit also features a proven PC board lay-
out, which can be easily duplicated for quicker time-to-
market. The EV kit Gerber files are available for down-
load at www.maxim-ic.com.
