General Description
The MAX1470 evaluation kit (EV kit) allows for a
detailed evaluation of the MAX1470 superheterodyne
receiver. It enables testing of the device’s RF perfor-
mance and requires no additional support circuitry. The
RF input uses a 50
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 MAX1470 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 250MHz to 500MHz. In addition, the 5kbps
data rate can be adjusted from 0kbps to 100kbps by
changing two more components.
For easy implementation into the customer’s design, the
MAX1470 EV kit also features a proven PC board layout,
which can be easily duplicated for quicker time to market.
The EV kit Gerber files are available for download at
www.maxim-ic.com.
