Analog Devices Sets New Performance Level with New Family of
High-Dynamic-Range,
Single-Channel Mixers
 March
3, 2009 - NORWOOD, Mass.--(EON:
Enhanced Online News)-- Adding to its broad portfolio of RF ICs,
Analog Devices, Inc. (ADI),
a world leader in high-performance semiconductors for signal-processing
applications, today introduced a family of five single-channel
RF mixers for high-dynamic-range applications within satellite communications,
wireless base stations, point-to-point radio links, instrumentation,
and military equipment.
Covering the 10-MHz to 6000-MHz range,
the
ADL5801 single-channel active mixer, which has the widest available
operating frequency, complements the ADL5802 dual-channel active mixer
announced in October 2008. The
ADL5355,
ADL5357,
ADL5365 and
ADL5367 high-performance, single-channel passive mixers, specified
for operation across the cellular frequency ranges, complement the
ADL5356,
ADL5358, and
ADL5360 dual-channel passive mixers.
ADL5801
Wideband Single-Channel Active Mixer
The
ADL5801 mixer, the industry’s first broadband single-channel device
to enable down- and up conversion of signals, is suitable for both
transmit and receive signal paths. The industry’s highest linearity
active mixer, the ADL5801 is packaged in a 4 mm × 4 mm LFCSP and consumes
50% less power than the competing passive devices. The ADL5801 single-channel
active mixer achieves 27-dBm IIP3 (third-order input intercept point)
with 10-dB single sideband noise figure. In addition, the ADL5801 provides
a conversion power gain of 1.5 dB, reducing the need for an additional
IF amplifiers.
Unique to the ADL5801, an on-chip input power detector
can be used to adjust the mixer bias. This adaptive bias feature allows
for optimal high IP3 performance when presented with large unwanted
interferers, often referred to as blocking signals. When blockers are
no longer present the ADL5801 automatically switches to a lower power
operating mode.
ADL5355, ADL5357 Single-Channel
Passive Mixers with integrated LO and IF Amplifiers
The
ADL5355 mixer operates over the 1500 MHz to 2500 MHz frequency range;
the
ADL5357 mixer operates over the 500 MHz to 1500 MHz frequency range.
With on-chip IF and LO amplifiers and input baluns, the mixers offer
the highest level of integration. The ADL5355 and ADL5357 mixers achieve
27-dBm IIP3 with 8.1-dB power conversion gain, and 9.4-dB single-sideband
noise figure. In high interference environments, where the noise figure
must not be degraded due to blocking, both products provide best-in-class
performance with better than 18-dB SSB noise figure in the presence
of an 10-dBm blocker.
ADL5365, ADL5367 Single
Passive Mixer with integrated LO Amplifier
The
ADL5365 mixer operates over the 1500MHz to 2500 MHz frequency range;
the
ADL5367 mixer operates over the 500 MHz to 1500 MHz frequency range.
Removing the IF amplifier allows the mixer to be configured for use
as either an up- or down converter.
Achieving the industry’s
lowest power conversion loss (–7 dB), the ADL5365 and ADL5367 mixers
provide 31-dBm input IP3 and 7.1-dB SSB noise figure. Featuring the
highest input linearity IP3 specifications, they are ideally suited
for use in transmit path observation receivers, and other applications
that operate with high input signal power.
No external components
are required on the RF or LO inputs to achieve these best-in-class results,
making them suitable for the highest performance integrated receiver
down conversion applications requiring a high-gain mixer. Unlike competitive
devices, the single-channel passive mixer family provides power-down
functions, and operates over a 3.3-V to 5-V supply voltage range, making
them suitable for power-sensitive applications.
Both new mixer
families, manufactured on an advanced SiGe bipolar process, provide
2000 V HBM ESD, simplifying handling procedures as compared to sensitive
GaAs mixers.
Availability and Pricing
The
ADL5801, ADL5355, ADL5357, ADL5365 and ADL5367 mixers and evaluation
boards are available to order in sample quantities. The ADL5801 is priced
at $5.15; the ADL5355, and ADL5357 are priced at $6.98; and the ADL5365
and ADL5367 are priced at $5.99 in 1000-unit quantities. For more information,
