SDR demonstration platform suit wireless data apps
The DE9941 credit card sized demonstration board for the CMX994 Direct Conversion Receiver, the CMX998 Cartesian Loop Transmitter and the CMX7164 Multi-mode Wireless Data Modem.
It is designed to be small and low-cost with minimal components/values and can be used to demonstrate Tx and Rx performance with QAM modulation, FSK and GMSK type modulation.
Together with the PE0002 host controller, a full transceiver can be demonstrated using a function mage and control scripts. The DE9941 provides a fractional-N PLL and VCO plus associated circuits to provide local oscillator signals for the CMX994 and CMX998. The PE0002, together with the control scripts, gives the user the ability to program the RF synthesiser to the correct operating frequencies.
The design also includes a 1 W PA, harmonic filter and Tx/Rx switch. The RF performance is designed to be compliant with EN 302 561 and EN 300 113, all the circuits are provided with power-down capability to allow standby functionality.(Contact company for pricing and availability)
