Analog Devices’ Quadrature Demodulators Offer Unprecedented
Levels of Dynamic Range and Integration
 NORWOOD,
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.
