Consumer Microcircuits Limited CMX992
the CMX992 is an RF Quadrature Receiver. It operates from 100MHz to 1GHz and its I/Q architecture supports multiple modulation types and bandwidths with a single radio design. The half-duplex CMX991 integrates Tx modulators, Rx demodulators, IF PLL and IF VCO subsystems to minimise the external circuits needed when implementing a complete transceiver.| Part No. | CMX992 |
