Analog Devices Introduces
High-Performance Analog Front End for 900 MHz Band RF Applications
The single-chip
ADF9010 combines a leading edge I/Q modulator with a low noise synthesizer,
including on-chip VCO, without compromising the performance of individual
RF blocks; significantly lowers system costs and greatly reduces time-to-market
NORWOOD, Mass.--(BUSINESS
WIRE)-- Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance
semiconductors for signal-processing applications, today announced the
availability of the ADF9010, a fully integrated RF Tx modulator and
Rx analog baseband for applications that operate in the 900 MHz frequency
range, including RFID readers, industrial, scientific and medical (ISM)
band radio communications devices, professional mobile radios, cellular
base stations and RF-over-coax applications. The ADF9010 integrates
a high-performance Tx quadrature modulator with an integer-N synthesizer
and on-chip low-phase-noise voltage-controlled oscillator (VCO), maintaining
superb RF performance and lowering system cost. When used in an RFID
application, for example, the combination of integration and performance
featured in the ADF9010 can result in a bill-of-material savings of
as much as 50 percent and board space reductions up to 70 percent, as
well as a substantial reduction in design cycle time as compared to
a multiple discrete component approach.
Analog Devices
will showcase the ADF9010 this week at the 2008 International Microwave
Symposium in Atlanta, Georgia (Booth #1743), together with other innovations
from ADI’s broad RF portfolio including PLL
and DDS synthesizers, clocks and timing ICs, RF amplifiers, demodulators,
RF detectors and more.
More about
the ADF9010 Analog RF Front End
The ADF9010
operates in the 840-MHz to 960-MHz frequency range, a level of performance
few other parts on the market today can deliver in such a highly integrated
form factor. The receive path consists of a fully differential I/Q baseband
programmable gain amplifier (PGA) and programmable low-pass filter (LPF).
The Rx LPF gain is programmable from 3 dB to 24 dB in 3-dB steps. The
Rx LPF features four programmable modes, with auto-calibrated cutoff
frequencies of 330 kHz, 880 kHz and 2 MHz. The filter can be bypassed
if necessary.
In addition,
the ADF9010 has a high performance integer-N PLL with fully integrated,
low noise VCO, achieving LO phase noise of –140
dBc/Hz at 1 MHz offset. This LO output signal is also available to drive
an external RF demodulator, such as Analog Devices’
ADL5382.
The transmit
path consists of a fully integrated differential Tx direct I/Q upconverter,
which converts a baseband I/Q signal to an RF carrier-based signal between
840 MHz and 960 MHz. The VCO runs at four times the LO frequency, and
the excellent quadrature, achieved via the subsequent divide-by-4 stage,
provides >45 dB sideband suppression.
The transmit path delivers OIP3 of 24 dBm, output P1 dB of +10 dBm and
output noise floor at –158 dBm/Hz.
Control
of all of the on-chip registers on the ADF9010 is achieved via a simple
3-wire serial interface. The device consumes 240 mA from a 3.3-V power
supply and can be powered down when not in use.
Availability
and Pricing
The ADF9010
analog RF front end is available now and comes in a 7 mm
× 7 mm 48-lead LFCSP package. The ADF9010
is priced at $11.98 per unit in 1,000-unit quantities. For more information,
