射頻正交/中頻（IF）接收器 CMX992Q3描述

CMX992：:RF Quadrature/Low IF Receiver
The CMX992 is a single-chip, high performance, RF receiver IC for analogue and digital radio systems. It operates from 100MHz to 1GHz and its I/Q architecture supports multiple modulation types and bandwidths with a single radio design.
The CMX992 integrates first mixer, Rx demodulators, IF PLL, and IF VCO subsystems that minimise the external circuits needed to implement a complete receiver. User-selected modes suit different application requirements.
The Rx path includes an integrated 1st Rx mixer having two outputs to support two external 1st IF filter choices, then an integrated 2:1 input mux followed by VGA and wideband signal level measurement functions to support AGC implementation.
The 1st IF signal is then either I/Q demodulated to zero IF or mixed to a low IF output.
The CMX992 provides differential and single-ended Rx output options and differential amplifiers for flexible signal conditioning.The CMX992 includes the core RF and IF functions of a high performance receiver and can be used in a wide range of narrowband and wideband wireless products including multi-mode analogue/digital terminals.
The CMX992 can be used where highly linear modulations are being used, e.g. for applications such as TETRA, where a typical transmitter solution would include the CMX998 Cartesian Feedback Transmitter.
