Product Description
The CMX973 integrates a quadrature (I/Q) modulator and a low-power quadrature IF/RF demodulator, both featuring a wide operating frequency range and optimised power consumption. The demodulator is suitable for superheterodyne architectures with IF frequencies up to 300MHz and the device may be used in low IF systems or those converting down to baseband. The modulator converts directly from baseband to the desired transmit frequency and features quadrature phase correction to minimise unwanted spectral components. An on-chip PLL and VCO, together with uncommitted baseband differential amplifiers, provide additional flexibility. Control of the CMX973 is by serial bus. The CMX973 is supplied in an RF_x0002_optimised 32-lead VQFN package.
