BGX7101

The BGX7101 device combines high performance, high linearity I and Q modulation paths for use in radio frequency up-conversion. It supports RF frequency outputs in the range from 400 MHz to 4000 MHz. The BGX7101 IQ modulator is performance independent of the IQ common mode voltage. The modulator provides a typical output 1 dB compression point (PL(1dB)) value of 12 dBm and a typical 27 dBm output third-order intercept point (IP3O). Unadjusted sideband suppression and carrier feedthrough are 50 dBc and −45 dBm respectively. A hardware control pin provides a fast power-down/power-up mode functionality which allows significant power saving.
