Product Preview PP/994/8 July 2019 CMX994, CMX994A, CMX994E & CMX994G Direct Conversion Receiver ICs With PowerTrade™ Low Power/ Enhanced Performance The CMX994/CMX994A/CMX994E/CMX994G is a family of direct conversion receiver ICs with very high IIP2 performance for use in zero IF, near-zero IF and low IF receivers. Power consumption is a key factor in many applications; PowerTrade™ provides the ability to dynamically select power consumption vs. performance modes to optimise operating trade-offs. The latest addition, the CMX994G, offers all the benefits of CMX994E with guaranteed performance down to 30MHz. Features  Direct conversion to Zero IF, Near-zero IF or low IF (Zero IF eliminates image responses) Baseband Signal Processor Data Modem  100 - 1000 MHz operation - CMX994A and CMX994E with extended operation 50 - 1218 MHz (30 - 1218 MHz guaranteed, CMX994G)  100 - 940 MHz CMX994  PowerTrade™ delivering flexible power vs. performance Direct Conversion Receiver  LNA with Gain control  Low power consumption  Very high mixer IIP2 for practical zero IF receiver  Mixer bandwidth up to 20MHz Systems Diagram  Tx LO Output with divide by 1, 2, 4 or 6 modes  3.0V - 3.6V low power operation Applications  Digital/analogue radio Small 40-pin VQFN Packages  Software Defined Radio (SDR)  Data telemetry modems  Satellite communications PowerTrade™ Feature  Narrowband 6.25kHz to wideband data >1MHz bandwidth Enhanced Performance  Highest integration for an RF Rx function  On-chip LNA with digital gain control  Minimum of external components  Smallest PCB area requirement  Overall lowest cost Rx solution  Precise filtering for digital compensation  Can be used in zero-IF, near zero-IF and low IF systems  Compatible with CMX998 CFB
