CML Microcircuits (USA) Inc. from CML Microcircuits

RF Direct Conversion Receiver IC

Status: Standard | Data Sheet:

| RoHS Compliance:

The CMX994EF replaces the prior generation of direct conversion receiver ICs from CML. CMX994EF has improved PowerTrade™, the ability to dynamically select power vs. performance modes to optimise operating trade-offs. The CMX994EF includes a broadband LNA with gain control followed by a high dynamic range, very high IIP2, I/Q demodulator. The receiver baseband section includes amplifiers and precise, configurable bandwidth, baseband filter stages. LO generation is provided by an integer-N PLL and a VCO negative resistance amplifier; an external LO may also be used. LO dividers are provided for flexible multi-band operation. The devices operate from a single 3.3V supply over a temperature range of –40°C to +85°C and are available in a small 40-pin VQFN (Q4) package.

The CMX994EF includes all the features of the CMX994A and CMX994E including the enhanced performance mode. The CMX994EF has a better transient response on power up/down allowing faster switching on/off and improved power-saving capability.
