CMX994E Direct Conversion Receivers

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. All four 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 .

Features
