Analog Devices Enhances RF/IF Signal
Chain Performance with Highly Integrated Synthesizer and Mixer Family
- ADI’s ADF4350 synthesizer features superior phase-noise performance;
couples with ADI’s new dual-channel active and passive mixers to enable
a highly linear RF front end for cellular base stations, satellite communications,
and point-to-point microwave radio equipment. NORWOOD,
Mass.--(BUSINESS
WIRE)-- Analog Devices, Inc. (ADI),
a world leader in high-performance semiconductors for signal processing
applications, today introduced the
ADF4350 synthesizer with on-chip
VCO (voltage-controlled oscillator) and
PLL (phase-locked loop), which is the industry’s first fully integrated
synthesizer to operate over an exceptionally wide continuous frequency
range. Also today, ADI introduced a family of highly integrated active
and passive mixers that are ideally suited for use in diversity communications
applications. The
active ADL5802 and
passive ADL5356,
ADL5358 and
ADL5360 dual-channel diversity mixers expand ADI’s portfolio of
main and diversity products and when coupled with the ADF4350 provide
a highly integrated two-chip diversity down conversion solution for
cellular base stations, satellite communications, and point-to-point
microwave radio equipment. The ADF4350 integrated synthesizer provides
designers with a single, low phase-noise solution supporting a continuous
tuning range from 137.5 MHz to 4.4 GHz. Alternative approaches require
as many as 10 individual VCO/PLL combinations. The VCO in ADI’s new
ultra-broadband, fully integrated synthesizer features phase-noise of
–137 dBc/Hz at a 1-MHz offset when operating at 2.1 GHz, and –155 dBc/Hz
at a 1-MHz offset when operating at 137.5 MHz. This corresponds to an
integrated rms phase error of 0.36 degrees at 2.1 GHz and 0.02 degrees
at 137.5 MHz. The ADF4350 provides two RF output ports and enables the
user to digitally program the output power level. Unlike competing
synthesizers, the ADF4350 supports both integer-N and fractional-N operating
modes, allowing the user to determine the optimal spur and phase-noise
performance via software controls for optimal performance and faster
time to market. New Dual Mixer Family Addresses High Dynamic
Range Applications ADI’s new mixer family includes the
ADL5802 wideband active device, which provides high linearity and modest
gain in the industry’s smallest package footprint. The family also includes
the ADL5356, ADL5358 and ADL5360 band-specific passive mixers, which
achieve high linearity and a low-noise figure with integrated IF (intermediate
frequency) amplifiers and offer higher gain compared to other active
and competing passive devices. The ADL5802 dual active mixer achieves
an IIP3 (third-order input intercept point) of 27 dBm and a single sideband
noise figure of 11 dB with a conversion power gain of 1.5 dB within
a 4 mm × 4 mm LFCSP (lead-frame chip-scale package). For high linearity
applications, the ADL5802 dissipates less than 1 W from a 5-V power
supply. The ADL5802 uses high linearity doubly-balanced active mixer
cores together with integrated LO (local oscillator) buffer amplifiers
to provide high dynamic-range frequency conversion from 300 MHz to 6
GHz. A bias-adjust feature allows the input linearity, single sideband
noise figure, and dc current to be optimized using a single control
pin. The ADL5356, ADL5358 and ADL5360 dual passive mixers with integrated
IF amplifiers and integrated RF (radio frequency) balun achieve an IIP3
of 26 dBm, a single sideband noise figure of less than 10 dB, and an
industry leading 10-dBm blocker noise figure of 16.5 dB. The passive
mixers with IF amplifiers provide a conversion power gain of 8.5 dB
to 9.5 dB within a small 6 mm x 6 mm LFCSP footprint. The 5-V (nominal)
ADL5356, ADL5358, and ADL5360 can also be operated on a 3.3-V supply
voltage for power-conscious applications. The new active and passive
mixers are well matched to ADI’s ADF4350 synthesizer. In addition, the
ADF4350 provides an ideal LO source for Analog Devices’
ADL538X demodulators and
ADL537x modulators. Together these products provide an ideal RF
receive signal path when combined with Analog Devices’
AD837X family of high dynamic range variable gain amplifiers and
Analog Devices’
ADL552X low-noise RF amplifiers. Availability and Pricing
