CML Microcircuits unveils its CMX993 highly integrated, general purpose, RF quadrature modulator that offers 100-MHz to 1-GHz operation and optimal wide-band noise performance. Additional features include gain control and uncommitted differential amplifiers. Targeted to meet the requirements of wireless data (digital TV, CATV modulators, ISM transmitters, Wireless LAN, WLL) and two-way radio systems (APCO P25), the device's I/Q architecture supports a range of modulation types. Various integrated, selectable functions are offered to maintain performance across multiple modulations and bandwidths. The modulator offers two integrated and matched double-balanced mixers, driven from a buffered quadrature split local oscillator.
