MAX1473 Evaluation Kit
General Description
The MAX1473 evaluation kit (EV kit) allows for a
detailed evaluation of the MAX1473 superheterodyne
receiver. It enables testing of the device’s RF perfor-
mance and requires no additional support circuitry. The
RF input uses a 50Ω matching network and an SMA
connector for convenient connection to test equipment.
The EV kit can also directly interface to the user’s
embedded design for easy data decoding.
The MAX1473 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. In addition, the 5kbps
data rate received can be adjusted from 0 to 100kbps
by changing two more components.
For easy implementation into the customer’s design, the
MAX1473 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.
