    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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Analog Devices Press Release - October 11, 2011

Analog Devices' Quadrature Demodulators Offer Unprecedented
Levels of Dynamic Range and Integration

Functional Block Diagram for ADRF6806NORWOOD, Mass.--( BUSINESS WIRE)-- Analog Devices, Inc. (ADI) today introduced the ADRF6806 and ADRF6807 quadrature demodulators featuring the industry's highest dynamic range and integration, which cover a wide range of IF frequencies used in QAM / QPSK receivers as well as supporting common cellular standards such as W-CDMA / CDMA2000 / LTE, and also microwave point-to-point and point-to-multi-point radio architectures. The ADRF6806 demodulator operates in the 50-MHz to 525-MHz LO range, and the ADRF6807 demodulator operates in the 700-MHz to 1050-MHz LO range. The ADRF6806 and ADRF6807 use a high performance mixer core that results in an exceptional input IP3 and input P1dB, with a very low output noise floor for excellent dynamic range. Both demodulators integrate an IQ demodulator with a high performance fractional-N phase-locked loop (PLL), a low noise voltage-controlled oscillator (VCO), and two low drop-out regulators (LDO). The ADRF6806 and ADRF6807 are the latest additions to ADI's family of integrated products which are the industry's only quadrature demodulators to combine three RF functions into a single device, thereby simplifying design and reducing board space and bill of materials cost. The ADRF6806 and ADRF6807 also feature multiple programmable functions through its SPI port which allows the user to control the fractional-N PLL, the demodulator LO divider, multiple optimization options, low power mode, as well as allowing for an externally applied LO, or to generate a divided-down VCO signal for external use. The ADRF6806 and ADRF6807 demodulators are designed on an advanced silicon-germanium BiCMOS process and available in a compact 6-mm x 6-mm LFCSP package.

ADRF6806 Quadrature Demodulator Key Features:
  • LO frequency range of 50 MHz to 525 MHz
  • Leading RF performance: Input P1dB of 12.2 dBm; Input IP3 of 28.5 dBm; Noise figure (DSB) of 12.2; Voltage conversion gain of 1.0 dB
  • Quadrature demodulation accuracy: phase accuracy of <0.5° and amplitude accuracy of <0.1 dB
    Baseband demodulation of 170 MHz, 3-dB bandwidth
  • SPI serial interface for PLL programming
ADRF6807 Quadrature Demodulator Key Features:
  • LO frequency range of 700 MHz to 1050 MHz
  • Leading RF performance: Input P1dB of 12.8 dBm; Input IP3 of 26.7 dBm; Noise figure (DSB) of 13.1; Voltage conversion gain of 1.0 dB
  • Quadrature demodulation accuracy: phase accuracy of <0.5° and amplitude accuracy of <0.1 dB
    Baseband demodulation of 170 MHz, 3-dB bandwidth
  • SPI serial interface for PLL programming
