New RF Building Block from CML Microcircuits

News

CML Microcircuits has released a new integrated quadrature IF/RF demodulator and quadrature modulator.

The CMX973 quadrature modulator/demodulator is the latest RF building block following on from the CMX970 and CMX971. The RF building block range is designed to provide flexible, high-performance ICs required for HF/VHF/UHF, professional radios, wireless data terminals, wireless microphones, marine and avionics radio systems.
The CMX973 is the basis of a high-performance RF transceiver system combining a flexible IF/RF quadrature modulator and quadrature demodulator in a single chip. Wide signal bandwidth at RF, 0dBm output, low noise and serial bus control delivers maximum flexibility and high-performance, all at an attractive low operating power.
The demodulator is suitable for superheterodyne architectures with IF frequencies of 20MHz to 300MHz and it may be used in low IF systems or those converting down to baseband. The modulator converts directly from baseband to the desired transmit frequency 20MHz to 1GHz and features quadrature phase correction to minimise unwanted spectral components.
