The new CMX972 features a low-power IF/RF Quadrature Demodulator with PLL/VCO, a wide operating frequency range and optimised power consumption. The demodulator is suitable for superheterodyne architectures with IF frequencies up to 300MHz and the device may be used in low IF systems or in those converting down to baseband.

CML Microcircuits is pleased to announce the release of a new Function Image and Datasheet for the CMX7011 Digital Voice Processor. With the new Function Image the CMX7011 is capable of Voice Store/Retrieve and Packet Data functionality. The CMX7011 is a flexible, half-duplex, digital voice processor that provides the digital advantage to conventional analogue two-way radios.

The CMX994 Direct Conversion Receiver integrates an LNA, a high IIP2 I/Q demodulator, DC offset trims, VGA with configurable IF filters, Rx LO frequency divider, Tx LO frequency divider and LO generation circuits to enable high performance, low power, small form factor multiband receivers to be implemented simply and at a low overall cost.

CML Microcircuits has released new Function Images for their successful CMX7131/7141 family of Digital PMR Processors. The new Function Images add to the already flexible device allowing it to be used in the design of small, low-cost, low-power digital and analogue PMR radios. Thanks to CML’s innovative chipset designing a small, low-cost, low-power analogue or digital PMR radio has now never been easier.

CML Microcircuits has today announced the introduction of the CMX188, Analogue Communications Enhancements Processor. The CMX188 ACE Processor is specifically targeted at providing the digital advantage to analogue two-way radios and walkie-talkies, serving both licence-free and licensed two-way radio market sectors.

CML Microcircuits has released a small demonstration platform for a complete Software Defined Radio for wireless data applications.

CML Microcircuits has today announced an expansion of its DuraTALK digital voice processor range with the release of a new professional radio low bit-rate 2.4kbps vocoder. The CMX7262 is a high-performance low bit-rate vocoder for professional two-way radio, providing market-leading crystal clear voice and excellent performance in real-life radio operation.

CML Microcircuits has released a new integrated Quadrature IF/RF Demodulator and Quadrature Modulator. The CMX973 Quadrature Modulator/Demodulator is the latest RF building block from CML Microcircuits following on from the CMX970 and CMX971.

CML Microcircuits has increased the operating range of its CMX994 Direct Conversion Receiver. Through an on-going research and development programme, CML has extended the operating range of the CMX994 Direct Conversion Receiver IC. Now operating over an RF range of 50MHz to 940MHz, the CMX994 now addresses a wider range of Software Defined Radio demands.

CML Microcircuits has released a new Quadrature Modulator Integrated Circuit. The CMX971 Quadrature Modulator is the latest RF Building Block from CML Microcircuits following on from the CMX970 IF/RF Quadrature Demodulator.

CML Microcircuits has released a Function Image Update for the high-performance CMX7164 Multi Mode Modem. Function Image 7164FI-1.x adds the use of GMSK/GFSK modulation and is the latest in a roadmap of function enhancements available through CML’s FirmASIC component technology. These updates are designed to add to the device’s functions and features, increasing its flexibility and facilitating in-the-field upgrades.

CML Microcircuits has released a new low power, IF/RF Quadrature Demodulator Integrated Circuit. The new CMX970 offers exceptionally low power consumption and high performance over the operating range of 20 to 250 MHz. Designed to meet the challenging requirements of Wireless Data and Analogue/Digital PMR/LMR radio systems, this product builds on the classic superheterodyne receiver technique to realise the ultimate low power IF/RF Quadrature De...

When the original QAM + RF YouTube video was created, our evaluation board recommendation for customers consisted of one PE0002 host. Since that time our customer recommendation for QAM + RF evaluation boards has evolved into using two PE0002 hosts. Consequently, the original video has been updated to reflect operation with two PE0002 hosts.

This video demonstrates the use of the CMX994 as part of a complete QAM (Quadrature Amplitude Modulation) datalink.

The CMX7861 ‘FirmCODEC’ is a full featured analogue front end for DSP/FPGA/Microcontroller based systems. The device is a combination of codec, embedded signal processing and auxiliary system support functions, allowing simple interfacing between analog and digital systems that together improve overall system performance, reduce development time and overall system cost.

CML Microcircuits has added a new Direct Conversion Receiver IC (DCRx) to its family of RF Integrated Circuits. The CMX994 targets the next generation of multi-mode Software Defined Radios (SDR) for wireless data and two-way radio applications. Its design provides the optimum route for on-board integration, allowing a small RF receiver to be realised with a minimum of external components in both zero IF and low IF systems.
