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.

CML’s proprietary FirmASIC® component technology reduces cost, time to market and development risk, with increased
flexibility for the designer and end application. 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).
