The MAX1471 evaluation system (EVSYS) is a complete receiver system consisting of a MAX1471 evaluation kit (EVKIT) and a Maxim CMAXQUSB module. Order the complete EVSYS (MAX1471EVSYS) for comprehensive evaluation of the MAX1471, using a personal computer (PC). Order the evaluation kit (MAX1471EVKIT) separately if the CMAXQUSB module has already been purchased with a previous Maxim system or when using a custom microcontroller-based system.
The MAX1471EVKIT provides a proven design to evaluate the MAX1471 ASK/FSK superheterodyne receiver in a TQFN package with an exposed pad. The EVKIT enables testing of the device’s RF performance while the EVSYS provides the added benefit of using a tested digital interface and software GUI. The RF input interface includes an SMA connector for convenient connection to test equipment.
The MAX1471EVKIT is available in two versions: 315MHz (MAX1471EVKIT-315) and 433.92MHz (MAX1471EVKIT-433). The passive components are optimized for these two frequencies but can easily be changed to work at RF frequencies from 300MHz to 450MHz.
There are separate data paths in the MAX1471 for ASK and FSK signals. In this EVKIT, both the ASK and FSK data filter bandwidths are set at 5 kHz, which is recommended for receiving a 4.2 kbps Manchester data rate.
For easy implementation into the customer’s design, the MAX1471EVKit also features a proven PCB layout, which can be easily duplicated for quicker time-to-market. The EVKIT Gerber files are available for download at www.maximintegrated.com.
