Communication modem module DE9941A

dataUHFFSK

The DE9941A is a compact UHF wireless data modem demonstration platform using the CMX994E Direct Conversion Receiver, the CMX998 Cartesian Feedback Loop Transmitter and the CMX7364 High Performance Multi-mode Wireless Data Modem. The credit card sized small form factor of the evaluation platform is due to the highly integrated nature of the CML IC solutions and its software defined architecture allows support of multiple channel bandwidths (12.5/25/50kHz) and modulation types with a single hardware design. Whilst the components used support operation from 100MHz to 1GHz the design is optimised for operation in the 350-400 MHz band. The board can be used to demonstrate receive and transmit performance with multi-level QAM, FSK and GMSK type modulation. Using the on-board ARM host controller, a full transceiver can be demonstrated interfacing to a host PC via USB, with scripts available to set up the board as a transceiver, as well as running BER tests and operation in transmit mode only.
