DE9941
SDR 1 Demonstrator
Soꢀware Defined Radio Demonstrator for Linear Radio Systems
Introducꢀon
DE9941 Brief Descripꢀon
There is a growing market
requirement for small , flexible
Soꢀware Defined Radio (SDR)
data modems.
The DE9941 is a small demonstraꢁon plaꢂorm for a linear modulaꢁon-based
Soꢀware Defined Radio (SDR) for wireless data applicaꢁons.
The small form factor of this credit card sized board is possible due to the high
integraꢁon of key funcꢁons 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.
Cartesian Loop Transmiꢃer - CMX998
Direct Conversion Receiver - CMX994
Mulꢁ-mode Wireless Data Modem - CMX7164
The DE9941 can be used to demonstrate transmit and receive performance with
4/16/64 QAM linear modulaꢁon and constant-envelope modulaꢁon schemes such as
2/4-level FSK and GMSK, that are also available on the CMX7164 Mulꢁ-mode
Wireless Data Modem.
The CMX998 is a market-leading
Cartesian Loop Transmiꢃer IC
providing opꢁmum PA
linearisaꢁon for non-constant
envelope/linear systems.
Included on board is a 1W power amplifier and RF performance is designed to be
compliant with EN 302 561
The CMX994 is the ulꢁmate
Direct Conversion Receiver,
providing direct conversion from
RF down to I/Q baseband.
The design is aimed to be small and low cost, with the minimal number of
components/values.
The CMX7164 mulꢁ-mode
Feature Summary
Wireless Data Modem IC, based
on FirmASIC® technology, offers
mulꢁple modulaꢁon schemes
that can be uploaded into the
device via Funcꢁon Image™. The
device supports both linear and
non-linear modulaꢁon schemes
(2-FSK, 4-FSK, GMSK, 4-QAM, 16-
QAM and 64-QAM).

CML’s proprietary FirmASIC® component technology reduces cost, ꢁme to market and development risk, with increased
flexibility for the designer and end applicaꢁon. FirmASIC® combines Analogue, Digital, Firmware and Memory
technologies in a single silicon plaꢂorm that can be focused to deliver the right feature mix, performance and price for
a target applicaꢁon family. Specific funcꢁons of a FirmASIC® device are determined by uploading its Funcꢁon Image™
during device iniꢁalizaꢁon. New Funcꢁon Images™ may be later provided to supplement and enhance device
funcꢁons, expanding or modifying end-product features without the need for expensive and ꢁme-consuming design changes. FirmASIC® devices provide
significant ꢁme to market and commercial benefits over Custom ASIC, Structured ASIC, FPGA and DSP soluꢁons. They may also be exclusively customised
where security or intellectual property issues prevent the use of Applicaꢁon Specific Standard Products (ASSP’s).
