Richardson RFPD Introduces High Dynamic Range
IQ Modulators and Demodulators from ADI

 March 7, 2012 Press Release

Richardson RFPD logo

-- Devices Feature Integrated PLL and VCO; Operate at up to 2.4 GHz
March 7, 2012 – La Fox, Illinois: Richardson RFPD, Inc. today announces immediate availability and full design support capabilities for a group of high performance quadrature modulators and demodulators for operation at frequencies up to 2.4 GHz from Analog Devices, Inc. (ADI). The devices offer a combination of performance, broadband operating frequency, and flexible device architecture that makes them ideal for a variety of wireless infrastructure applications, including 2G, 2.5G and 3G cellular base station radios, high-capacity point-to-point and point-to-multipoint radio links, wireless LAN and aerospace and defense equipment.

The ADRF6806 and ADRF6807 are high dynamic range IQ demodulators with integrated PLLs and VCOs. The fractional-N PLL/synthesizer generates a frequency in the range of 2.8 GHz to 4.2 GHz. A programmable quadrature divider divides the output frequency of the VCO down to the required local oscillator (LO) frequency to drive the mixers in quadrature. Additionally, an output divider generates a divided-down VCO signal for external use.
The ADRF6806 and ADRF6807 are high dynamic range IQ demodulators with integrated PLLs and VCOs.ADRF6806 Features:
• LO Frequency Range: 50 to 525 MHz
• IQ Frequency: 135 MHz
• Phase Error: 0.5 Deg
• Amplitude Error: 0.1 dB
• OIP3: +28.5 dBm
• Noise Figure: 12.2 dB

ADRF6807 Features:
• LO Frequency Range: 700 to 1050 MHz
• IQ Frequency: 170 MHz
• Phase Error: 0.5 Deg
• Amplitude Error: 0.1 dB
• OIP3: +26.7 dBm
• Noise Figure: 13.1 dB
The ADRF6701 and ADRF6702 provide quadrature modulator and synthesizer solutions within a small 6 mm x 6 mm footprint while requiring minimal external components. The low phase noise voltage controlled oscillator (VCO) and high performance quadrature modulator make the devices suitable for next generation communications systems requiring high signal dynamic range and linearity. The integration of the IQ modulator, phase-locked loop (PLL), and VCO provides for significant board savings and reduces the bill-of-materials (BOM) and design complexity.
ADRF6701 Features:
• RF Frequency Range: 400 to 1300 MHz
• IQ Frequency: 500 MHz
• Carrier Suppress: -45 dBm
• Sideband Suppress: -40 dBc
• Noise Floor: -158 dBm/Hz
• Output P1dB: +14 dBm
• OIP3: +29 dBm
• Voltage Supply: 4.75 to 5.25V
• Supply Current: 210 mA

ADRF6702 Features:
• RF Frequency Range: 1200 to 2400 MHz
• IQ Frequency: 750 MHz
• Carrier Suppress: -46.8 dBm
• Sideband Suppress: -44.4 dBc
• Noise Floor: -157.8 dBm/Hz
• Output P1dB: +13.1 dBm
• OIP3: +29.1 dBm
• Voltage Supply: 4.75 to 5.25V
• Supply Current: 240 mA

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
