Expanding the company’s family of RF chips, the CMX993 general-purpose RF quadrature modulator operates over a bandwidth from 100 MHz to 1 GHz and integrates gain control and uncommitted differential amplifiers. Addressing the requirements of digital TV, CATV modulators, ISM transmitters, Wireless LAN, and WLL applications as well as two-way radio systems (APCO P25), the device’s I/Q architecture supports a wide range of modulation types. It packs two matched double-balanced mixers, driven from a buffered quadrature split local oscillator. The LO frequency is divided by either 2 or 4, with the mixers forming an I/Q vector modulator with programmable gain stages, offering 30 dB of gain control in 2.5-dB steps. The CMX993 operates at 3.3V (1.8V I/O) and comes in a 48-pin VQFN package. An evaluation kit, the EV9930, is also available. CML MICROCIRCUITS INC., Winston-Salem, NC. (800) 638-5577.
