Analog Devices Delivers Radio Frequency ICs with Breakthrough Integration
for Broadband Communications Equipment
Monolithic RF IC products reduce component count by more than 75 percent in point-to-point radios, wireless
base stations, cable infrastructure, and communications test equipment.
Analog Devices, Inc.
(NYSE: ADI), a global leader in high performance semiconductors for signal processing applications and leading
supplier of RF ICs (radio frequency integrated circuits), announced today two new RF ICs for broadband
communications systems that reduce component count by more than 75 percent, without compromising performance. The
ADRF6655 active mixer or
ADRF6510 dual programmable filter and VGA (variable gain amplifier) integrate multiple functions and discrete
devices into a single monolithic chip, reducing component count by a factor of four when compared to traditional
discrete RF designs. ADI is the only RF IC supplier to offer devices with this level of integration and with the
capability to address multiple broadband communications markets, such as point-to-point microwave radios, wireless
base stations, cable infrastructure, defense wideband and software-defined radios, cellular repeaters and relays,
and communications test equipment.

next-generation radio equipment constantly aim to reduce component count and system cost, without sacrificing
performance. ADI’s new ADRF6655 integrated broadband mixer and ADRF6510 dual programmable filter and VGA establish
new benchmarks in integration, based on our performance-leading and field-proven PLL/VCO, mixer and amplifier
technologies,” said Peter Real, vice president, Linear and RF products, Analog Devices. “Both devices solve
complex integration challenges for broadband RF system designers who have previously been constrained by the use
of multiple discrete circuits and who can now realize new levels of performance and cost efficiency with these
highly integrated and highly flexible monolithic RFICs.”
About the ADRF6655 Active Mixer Operating
within the 100 to 2500 MHz frequency range, the ADRF6655 device is a highly-flexible, single-chip, broadband,
active mixer with a fully integrated fractional-N phase locked loop (PLL) synthesizer, voltage controlled
oscillator (VCO) and associated low dropout (LDO) regulator circuits. The ADRF6655 active mixer is a highly
flexible device that provides exceptional performance for both up- and down-conversion applications. The PLL and
VCO provide a fully integrated LO (local oscillator) circuit that can also be brought off-chip for external use.
The ADRF6655 active mixer operates on a single +5 V supply and features input linearity IP3 (+29 dBm); input
compression P1dB (+14 dBm); conversion gain (6 dB), noise figure (12 dB) as well as LO phase noise of -111 dBc at
100 kHz offset. Full specifications and a complete data sheet can be accessed at
About the ADRF6510 Dual Programmable Filter and VGA The ADRF6510 is dual channel fully-differential baseband
signal processing solution that integrates a matched pair of fully differential low-noise and low-distortion
programmable filters and variable gain amplifiers onto a single chip. The ADRF6510 is the first monolithic IC that
replaces complex, bulky discrete fixed function filters, saving considerable board area. The matched filter
networks provide exceptional flexibility as the corner frequency is fully adjustable in 1 MHz steps, thereby
enabling wideband and narrow band support within a single radio design, a key benefit since the available spectrum
and bandwidth varies across markets and regions worldwide.
The ADRF6510 VGA provides an adaptable
multi-stage adjustable gain control range of 50 dB, a pre-amp prior to the filters provide a 6 dB step; while the
variable gain amplifiers that follow the filter networks provide gain range of -5 dB to +45 dB. This allows the
user to select and optimize the gain range for high dynamic range radios and eases the drive requirements into the
analog to digital converter.
The ADRF6510 is a unique industry first single chip solution that provides
low distortion >60dBc IMD3 ideally suited for high order QAM modulation, quadrature (I-Q) communications systems
supporting high bandwidth signals up to 56 MHz. A complete data sheet is available at
Availability and Complementary Products The ADRF6655 is available now in a 6 mm x 6 mm 40-pin LFCSP package and is
priced at $9.98 per unit in 1,000-unit quantities. The ADRF6655 is complemented by ADI’s RF/IF amplifiers such as
ADL5320. The ADRF6510 is available now in a 5 mm x 5 mm 32-pin LFCSP package and is priced at $8.99 per unit
in 1,000-unit quantities. The ADRF6510 is well-suited for use with ADI’s
ADL5387 wideband demodulators.
