Product Preview PP/9941/1 November 2015 DE9941 SDR 1 Demonstrator Software Defined Radio Demonstrator for Linear Radio Systems Introduction DE9941 Brief Description There is a growing market requirement for small , flexible Software Defined Radio (SDR) data modems. The DE9941 is a small demonstration platform for a linear modulation-based Software Defined Radio (SDR) for wireless data applications. The small form factor of this credit card sized board is possible due to the high integration of key functions comprising: The technology to accomplish this is now available with the release of CML’s highly integrated RF and baseband product offerings: CMX998, CMX994 and CMX7164. The CMX998 is a market-leading Cartesian Loop Transmitter IC providing optimum PA linearisation for non-constant envelope/linear systems. The CMX994 is the ultimate Direct Conversion Receiver, providing direct conversion from RF down to I/Q baseband. The CMX7164 multi-mode Wireless Data Modem IC, based on FirmASIC® technology, offers multiple modulation schemes that can be uploaded into the device via Function Image™. The device supports both linear and non-linear modulation schemes (2-FSK, 4-FSK, GMSK, 4-QAM, 16QAM and 64-QAM). Cartesian Loop Transmitter - CMX998 Direct Conversion Receiver - CMX994 Multi-mode Wireless Data Modem - CMX7164 The DE9941 can be used to demonstrate transmit and receive performance with 4/16/64 QAM linear modulation and constant-envelope modulation schemes such as 2/4/8/16-level FSK and GMSK, that are also available on the CMX7164 Multi-mode Wireless Data Modem. Included on board is a 1W power amplifier and RF performance is designed to be compliant with EN 302 561 The design is aimed to be small and low cost, with the minimal number of components/values.

FirmASIC® combines Analogue, Digital, Firmware and Memory technologies in a single silicon platform that can be focused to deliver the right feature mix, performance and price for a target application family. Specific functions of a FirmASIC® device are determined by uploading its Function Image™ during device initialization. New Function Images™ may be later provided to supplement and enhance device functions, expanding or modifying end-product features without the need for expensive and time-consuming design changes. FirmASIC® devices provide significant time to market and commercial benefits over Custom ASIC, Structured ASIC, FPGA and DSP solutions. They may also be exclusively customised where security or intellectual property issues prevent the use of Application Specific Standard Products (ASSP’s).
