Analog Devices Press Release - 3/3/2009
Analog Devices Sets New Performance Level with New Family of
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
RF mixers for high-dynamic-range applications within satellite communications, wireless base stations,
point-to-point radio links, instrumentation, and military equipment.
High-Dynamic-Range, Single-Channel Mixers
Covering the 10-MHz to 6000-MHz
ADL5801 single-channel active mixer, which has the widest available operating frequency, complements the
ADL5802 dual-channel active mixer announced in October 2008. The
ADL5367 high-performance, single-channel passive mixers, specified for operation across the cellular
frequency ranges, complement the
ADL5360 dual-channel passive mixers.
Wideband Single-Channel Active Mixer
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.
Single-Channel Passive Mixers with integrated LO and IF Amplifiers
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
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
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.
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, visit:
