Analog Devices Variable Gain Amplifiers Provide Unprecedented Levels
of Performance and Integration at RF and IF Frequencies
- Highly integrated SiGe BiCMOS and GaAs RF/IF variable gain control amplifiers combine multiple
functions in single chip, achieving significant BOM savings and breakthrough radio performance.
NORWOOD, Mass.--(BUSINESS WIRE)--
Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing
applications and RF integrated circuits, today introduced a series of highly integrated RF/IF variable gain
amplifiers (VGAs). ADI’s new
ADL5201,
ADL5202,
ADL5240 and
ADL5243 variable gain amplifiers offer breakthrough levels of integration—combining up to four discrete RF/IF
blocks into a single device. With this unprecedented level of integration, radio system manufacturers can realize
a significant reduction in component count and a major savings in BOM (bill of materials) cost. In addition to
unsurpassed integration, the new VGAs offer industry-leading performance, linearity and flexibility that make them
well-suited for demanding applications, such as cellular base stations, industrial/instrumentation and defense
equipment.
“These new RF / IF variable gain amplifiers further expand ADI’s commitment to offering
best-in-class levels of integration and performance for both RF and IF applications,” said Peter Real, vice
president, Linear and RF products, Analog Devices. “Both product families provide the user with flexibility to
select their preferred parallel or serial formats, and offer fine 0.5dB digital gain steps. This approach
simplifies and eases system design, decreases footprint and enables designers of equipment such as next generation
base stations to reduce component count, board area, supply lines and cost.”
 About
the ADL5201 and ADL5202 IF Variable Gain Amplifiers
The
ADL5201 and its dual version, the
ADL5202, are digitally controlled, IF variable gain amplifiers designed to support high IF sampling receiver
designs that require precise gain control, high IP3 and a low noise figure for new broadband radio designs. The
new VGAs combine highest dynamic range with lowest distortion and noise figures for IF frequencies up to 400 MHz.
The
ADL5201 and
ADL5202 are ideally suited for driving high-speed, next generation ADCs such as ADI’s AD9268. The new VGAs
incorporate proprietary distortion cancellation techniques that enable them to achieve the industry’s highest
linearity at more than 47 dBm output IP3 and noise figure of 6 dB. The ADL5201 and ADL5202 provide gain control
range of 31.5 dB with 0.5 dB resolution and are capable of supporting serial and parallel interface modes. The
ADL5201 and ADL5202 were developed on an advanced SiGe BiCMOS process which enables the reduction in component
count, power and supply voltages.
 About
the ADL5240 and ADL5243 IF/RF VGAs
Operating in the 100 MHz to 4000 MHz frequency range, the
ADL5240 and
ADL5243 RF/IF digitally controlled VGAs offer unsurpassed gain control performance and accuracy. Designed with
GaAs technology, the
ADL5240 VGA combines a DSA (digital step attenuator) and a gain block into a single IC, while the
ADL5243 combines a DSA, a gain block, and a broadband ¼ W driver amplifier in a single IC, without any
sacrifice in performance. Either the amplifier or the DSA can be first in the signal chain, maximizing system
flexibility by allowing the VGA to be used in multiple places throughout a design. The DSA in each VGA offers a
wide gain control range of 31.5 dB in 0.5 dB steps, and accommodates serial and parallel interface modes, while
the gain block in each VGA offers a very high linearity of greater than 40 dBm and noise figure of 2.9 at 900 MHz.
The ADL5243’s ¼ W driver offers industry- leading linearity performance of 42.0 dBm with an impressive 25.7 dBm
P1dB at 2.14 GHz.
