Description

The CMX994 /CMX994A /CMX994E /CMX994G is a family of direct conversion receiver ICs with PowerTrade™, the ability to dynamically select power vs. performance modes to optimise operating trade-offs. Standard and low power modes Standard and additional low power modes Enhanced, standard and low power modes Enhanced, standard and low power modes, 30MHz guaranteed performance The CMX994/A/E/G offer exceptional blocking performance, typical values are in the range 98dB to 102dB depending on the measurement method. All three devices include 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 CMX994/A/E/G operates 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.
