RF modulator targets wireless infrastructure

RF modulator targets wireless infrastructure

Operating from 30 MHz to 1 GHz, the CMX993W wideband quadrature modulator provides translation from baseband I/Q signals to a modulated RF signal. Its wideband inputs (up to 100 MHz) can be driven single-ended or differentially.

The part offers two integrated and matched double-balanced mixers, driven from a buffered, quadrature, split local oscillator. The “LO” frequency is divided by either 2 or 4, with mixers forming an I/Q vector modulator with programmable gain stages (offering a desirable 30 dB of gain control in 2.5-dB step increments). Housed in a 48-pin VQFN package, the chip operates at 3.3 V (1.8 V I/O). ($4.76 ea/10,000 — available now.)
