The CMX994GQ4 is a direct conversion receiver IC designed for applications requiring operation in the frequency range of 30MHz to 1.218GHz. It features a single conversion to zero IF, which helps eliminate image responses, and includes a broadband low noise amplifier (LNA) with gain control. The device supports a high dynamic range with very high IIP2, making it suitable for practical zero IF receiver applications. This receiver operates from a single 3.3V supply and is housed in a compact 40-pin VQFN package. It includes an I/Q demodulator capable of handling bandwidths from 100MHz to 1GHz, with extended operation down to 30MHz. The CMX994GQ4 also offers flexible local oscillator (LO) generation with integer-N PLL and VCO negative resistance amplifier, allowing for multi-band operation through LO dividers. The device is suitable for various applications, including software-defined radios, data telemetry modems, and satellite communications. It is designed to optimize power versus performance with its PowerTrade,Ñ¢ feature, allowing dynamic selection of operating modes. The CMX994GQ4 operates over a temperature range of -40¬8C to +85¬8C, making it versatile for different environmental conditions.
