Analog Devices Adds Direct
Conversion Receiver Solution for Next Generation Cellular and Broadband
Wireless to RF Portfolio
- Demodulator and dual-channel digital gain trim amplifier reduce component
count up to 60 percent.
NORWOOD, Mass.--(BUSINESS
WIRE)-- Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance
semiconductors for signal processing applications, continues to expand
its radio frequency (RF) product portfolio, adding a new quadrature
demodulator and dual gain trim amplifier for direct conversion receivers
in next-generation cellular 3G / 4G and broadband wireless 802.16 applications.
The ADL5380 demodulator is the industry’s
first product capable of operating from 400 MHz to 6 GHz, which allows
radio designers to apply the same device across a range of products
and frequency variants. The companion AD8366
is the industry’s first dual-channel digital
gain trim amplifier (DGTA) and is designed to enable, integrate and
cost reduce direct conversion radio receivers.
The combined two-chip solution can reduce the active component count
by 60 percent within a radio design, providing considerable board area
and bill of material (BOM) savings.
With the ADL5380 demodulator, base station receivers can be designed
for a variety of cellular and broadband wireless data systems and standards
including CDMA, W-CDMA, TD-SCDMA, PHS, LTE, and WiMAX. The ADL5380 is
also an ideal solution for defense and avionics equipment, including
software-defined radio, due to the broad operating frequency range and
wideband demodulation bandwidth. The AD8366 is optimized for signal
gain control and accuracy providing 0.25dB fine step resolution AGC,
with adjustable common mode and DC offset correction features for simplifying
direct conversion receivers and easing subsequent driving of the final
analog-to-digital converter (ADC).
“Analog Devices new demodulator and dual channel amplifier further
expands ADI’s leadership in high-performance,
highly integrated RF ICs,” said Peter Real,
vice president, Analog Devices. “Providing
utmost flexibility, integration and high linearity enables our customers
to design and implement the most cost-effective wireless infrastructure
direct conversion receivers for a variety of radio platforms, from single
standard radios, such as WiMAX to more complex multi-standard radios,
such as W-CDMA, LTE, and multi carrier GSM. By offering wide operating
frequency range and signal bandwidth support, our customers are able
to standardize on a solution across multiple platforms and projects.”
400 MHz to 6 GHz Quadrature Demodulator –
ADL5380
The ADL5380 covers the RF frequency range of 400 MHz to 6 GHz, offering
the industry’s highest dynamic range with
the highest linearity specifications, exemplified by second- and third-order
intercept point specifications of 31 dBm and 60 dBm respectively at
2500 MHz. Combining best-in-class linearity specifications with the
ability to handle the highest of interference signals and minimal noise
contributions ensures the highest receiver dynamic range is maintained,
under complex, realistic interfering situations, a critical requirement
for direct conversion receivers. In addition to high linearity, the
ADL5380 provides typical 3-4 dB of conversion gain, helping to minimize
the gain requirements of the receiver front end.
500 MHz Matched Dual, Digital Gain Trim Amplifier
– AD8366
The AD8366 is the industry’s first dual-channel
digitally controlled gain trim amplifier with 0.25 dB step over 4.5
to 20.5dB gain range. The AD8366 is ideally suited for analog I/Q quadrature
ADC driving, maintaining excellent quadrature accuracy for direct conversion
radio receivers. The fine gain control allows flexible and precise tuning
of gain-critical to multi-standard and wideband radio receivers. Additionally
the AD8366 features include adjustable output common mode for matching
to ADC input ranges, and DC output offset correction loops to minimize
demodulator DC offsets. The AD8366 is fully specified for direct conversion
receiver designs capable of handling the widest of signal bandwidths
with the lowest distortion. For example, the AD8366 supports the second
and third harmonic distortion >88 dBc for 10 MHz signals at max gain.
Pricing and Availability
The ADL5380 demodulator is available in a 24-lead 4 mm x 4 mm LFCSP
package and priced at $5.22 per unit in 1,000-unit quantities. The AD8366
DGTA is available in a 32-lead 5 mm x 5 mm LFCSP package and is priced
at $6.49 per unit in 1,000-unit quantities. For more information, please
