Quadrature Modulators Include Fractional-N PLL Synthesizers and Low Phase Noise VCOs
Richardson RFPD, Inc. today announces immediate availability and full design support capabilities for a pair of new integrated IQ modulators from Analog Devices, Inc. (ADI). The devices are the latest additions to ADI's range of quadrature modulator and synthesizer solutions that offer small footprints and require minimal external components. Both are suitable for next generation communications systems requiring high signal dynamic range and linearity, including cellular systems like GSM/EDGE, CDMA2000, W-CDMA, TD-SCDMA and LTE, as well as broadband wireless access systems and satellite modems. The integration of the IQ modulator, phase locked loop (PLL), and voltage controlled oscillator (VCO) provides for significant board savings and reduces the materials cost and design complexity.
The ADRF6703 is designed for RF outputs from 1550 MHz to 2650 MHz. Key features include:
- Internal LO frequency range: 2100 to 2600 MHz
