CML Microcircuits' CMX994x direct conversion receivers feature PowerTrade™ which provides the ability to dynamically select power versus performance to suit different system requirements. The devices convert RF signals in a 100 MHz to 1,000 MHz range directly down to the I/Q baseband or low IF. The low power consumption makes the receivers an ideal choice for battery-operated and portable applications. The CMX994A receiver is the standard version with low-power modes and the CMX994E receiver is an enhanced version with improved inter-modulation performance modes.
The CMX994x devices offer exceptional blocking performance to reject strong off-channel signals with measured values greater than 100 dB. The devices include an LNA with gain control followed by a high dynamic range, high-linearity (IIP2 ~79 dBm) I/Q demodulator with baseband filtering and gain control.
