Industry's Highest Performance Broadband Modulator & Demodulator
Enable Direct Conversion Cellular Basestations
ADI's ADL5375 quadrature modulator and ADL5382 demodulator simplify
RF-to-baseband designs and enable engineers to extend solutions to subsequent
wireless infrastructure system designs.
ADI is extending its RF
portfolio with the industry's highest performance broadband direct conversion
radio solution: the ADL5375 I-Q modulator and companion ADL5382 I-Q
demodulator. With the industry's broadest operating frequency ranges,
the ADL5375 and ADL5382 devices enable equipment designers to implement
and standardize on solutions that address the wide range of operating
frequency bands and standards, including GSM/EDGE, CDMA 2000, and W-CDMA,
eliminating the need to select a modulator or demodulator for each cellular
standard and operating band. Furthermore, designers can now implement
one common radio platform for cellular standards as well as broadband
wireless 802.16 WiMAX standards, which are increasingly being designed
using direct conversion radio architectures.
400 MHz to 6 GHz
Transmit Quadrature Modulator - ADL5375 The ADL5375 offers the industry's
highest dynamic range across the broadest frequency range--400 MHz to
6 GHz--a key attribute for direct up conversion transmitter architectures.
The ADL5375 combines the industry's highest linearity with 24-dBm output
IP3, the highest linear output power with +10-dBm P1dB, and a low -161-dBm/Hz
noise floor. The ADL5375 provides unadjusted sideband suppression of
-55 dBc and unadjusted carrier feed-through of -41 dBm, helping to eliminate
the need for calibration circuitry among the most demanding of applications
within cellular 2G and 3G radios. In addition, the ADL5375 allows the
user to shut down the transmitter, simplifying receiving of small signals
in time division applications, such as WiMAX and TDS-CDMA.
MHz to 2.7 GHz Receive Quadrature Demodulator - ADL5382 The ADL5382
covers the RF frequency range of 700 MHz to 2.7 GHz, offering the industry's
highest dynamic range with the highest linearity specifications, exemplified
by second and third order intercept point specifications of 60-dBm IP2
and 30-dBm IP3, and highest input compression of 13-dBm P1dB. Combining
these key specifications with the ability to handle the highest of interference
signals with minimal noise contributions ensures that the receiver dynamic
range is maintained, a critical requirement for direct conversion receivers
and now practical across the ADL5382's broad operating frequency range.
With integrated baseband output amplifiers, the ADL5382 reduces external
parts count and simplifies subsequent filter design. Furthermore, the
ADL5382 provides approximately 5 dB of conversion gain, helping to minimize
the gain requirements of the receiver front end.
The ADL5375 quadrature modulator is available
in full production and is priced at $4.98 per unit in 1,000-piece quantities.
The ADL5382 quadrature demodulator is sampling now and will be available
in full production quantities in March 2008. It is priced at $5.22 per
unit in 1,000-piece quantities. Both are available in 24-lead LFCSP_VQ
(lead-frame chip-scale packages). For more information, visit

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...
