Maldon, Essex - CML Microcircuits (www.cmlmicro.com), a leading innovator and provider of low-power semiconductors for global wireless and two-way radio communications markets, has released the CMX994A and CMX994E Direct Conversion Receiver (DCRx) ICs.

The CMX994A and CMX994E are RF receiver Integrated Circuits (ICs) featuring I/Q demodulators with low power consumption and high performance features. These devices are targeting the next generation of narrowband and wideband Software Defined Radios (SDR) for wireless data and two-way radio applications. Their design provides the optimum route for high integration, allowing a small RF receiver to be realised with a minimum of external components in zero-IF, near zero-IF and low-IF systems.

The CMX994A and the CMX994E ICs build on the success of the popular CMX994 and are the first devices to use CML's PowerTradeTM technology. PowerTradeTM enables the devices to dynamically balance power consumption and performance characteristics to suit varying operating requirements. Very low power consumption can also be achieved in standby mode whilst looking for an RF signal, using intelligent control of power cycling, phase control and I/Q channel selection.

The CMX994A delivers a very low power DCRx device while the CMX994E also includes the low power mode of the CMX994A but in addition, offers a high performance mode with improved IP3 performance.

The CMX994, CMX994A and CMX994E DCRx ICs offer excellent RF performance, exceptional IP2 from I/Q mixers and are suitable for modulation schemes including: QAM, 4FSK, GMSK and pi/4-DQPSK. Key features of the device include on-chip VCO for VHF applications, on-chip LNA, precision baseband filtering with selectable bandwidths and the smallest PCB area, typically less than 50% of a dual superhet.

The CMX994A and CMX994E are available now, operating at 3.0 - 3.6 V, and come in a Q4 40-pin VQFN package. For the datasheet, application notes and product support information, visit CML: www.cmlmicro.com.
