Product Details

The MAX1470 evaluation kit (EV kit) allows for a detailed evaluation of the MAX1470 superheterodyne receiver. It enables testing of the device's RF performance 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 MAX1470 EV kit comes in two versions: a 315MHz version and a 433.92MHz version. The passive components are optimized for these frequencies. These components can easily be changed to work at RF frequencies 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.maximintegrated.com.
