TI is introducing the TRF372017, an IQ modulator with integrated PLL (phase-locked loop) and wideband VCO (voltage crystal oscillator). The TRF372017 IQ (In-phase Quadrature) modulator provides 300 MHz to 4.8GHz continuous tuning range, enabling developers to eliminate the need for an external Local Oscillators. Targeted to wireless infrastructure market, the TRF372017 IQ modulator qualify all 3GPP and 3GPP2 standards, as well as licensed WiMAX.
