Product Details

The low cost and small profile EVAL-ADF7242-PMDZ is a 2.4 GHz, 802.15.4 wireless transceiver board that supports RF to FPGA or processor applications system that utilize PMOD-compatible expansion ports configurable for SPI communication (packet mode). For applications that require data streaming, a synchronous bidirectional serial port (SPORT) interface is also available. The wireless transceiver PMOD board can be configured to operate on the 2400 MHz to 2483.5 MHz ISM band. The board uses a single ADF7242 transceiver.

The EVAL-ADF7242-PMDZ board uses two mini 2.4 GHz chip antennas, an impedance-matched filter, and a balun for minimum RF front-end parts count. The board supports antenna diversity (polarization diversity) and uses two chip antennas mounted orthogonally, which greatly improves performance under multipath fading conditions.
