RF demodulator CMX970

quadrature

The CMX970 is a low power IF/RF quadrature demodulator, featuring a wide operating frequency range and low power consumption. Suitable for architectures with IF or RF frequencies up to 300MHz, the device may be used in low IF systems or those converting down to baseband. Control of the CMX970 may be either by serial bus or by direct control (with reduced functionality). The small, RF-optimised VQFN package and minimal external components make the device ideal for space-constrained applications. Programmable features include the local oscillator divider ratio (2 or 4). The demodulator has best in class intermodulation performance, excellent phase and amplitude balance and has two gain control elements which can be independently controlled. 20 – 300 MHz IF/RF Demodulator with VGA 10MHz I/Q Bandwidth Serial Bus or Direct Control Operation < 1 degree I/Q Phase Matching < 0.5 dB I/Q Gain Matching Low Power 15mA @ 3.3V Small 16-lead VQFN Package Wireless Data Terminals HF/VHF and UHF Mobile Radio Avionics Radio Systems Software Defined Radio (SDR) 3.0 to 3.6 V power supply
