The versatile CML Microcircuits CMX994 direct-conversion receiver IC (DCRx) fits an incredible array of applications, including the next generation of multi-mode software defined radios (SDRs) for wireless data and two-way radio applications. Its design and small size allow a small RF receiver to be realized with a minimum of external components in both zero-IF and low-IF systems.
