-- Quadrature Modulators Include Fractional-N PLL Synthesizers and Low Phase Noise VCOs

May 8, 2012 – Lafox, Illinois: 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 MHz to 2600 MHz
  • Output P1dB: 14.2 dBm @ 2140 MHz
  • Output IP3: 33.2 dBm @ 2140 MHz
  • Noise floor: −159.6 dBm/Hz @ 2140 MHz
  • Baseband bandwidth: 750 MHz (3 dB)
  • SPI serial interface for PLL programming
  • Integrated LDOs and LO buffer
  • Power supply: 5 V/240 mA
  • 40-lead 6 mm × 6 mm LFCSP
The ADRF6704 is designed for RF outputs from 2050 MHz to 3000 MHz. Key features include:
  • Internal LO frequency range: 2500 MHz to 2900 MHz
  • Output P1dB: 12.1 dBm @ 2700 MHz
  • Output IP3: 27.2 dBm @ 2700 MHz
  • Noise floor: −158.3 dBm/Hz @ 2700 MHz
  • Baseband bandwidth: 750 MHz (3 dB)
  • SPI serial interface for PLL programming
  • Integrated LDOs and LO buffer
  • Power supply: 5 V/226 mA
  • 40-lead 6 mm × 6 mm LFCSP
Common configurations are in stock and available for immediate delivery.
