SAN JOSE, Calif., and SINGAPORE, June 19, 2012 (GLOBE NEWSWIRE) --
Avago Technologies (Nasdaq:AVGO), a leading supplier of wireless
components for cellular base stations, macrocells, other communications
subsystems, and GPS/GLOSNASS positioning systems, today announced the
availability of multiple new wireless products targeted at macrocell
and small cell base stations and portable GPS systems.
"Driven by the unrelenting demand for connectivity everywhere and the
huge growth in cellular traffic, picocells and femtocells are helping
to offload the macrocells in a heterogeneous network of macrocells and
small cells," explains Allen Chien, Product Manager for Wireless
Products. "Leveraging our industry-leading products and technology for
mobile phones and base stations, Avago is delivering new products that
deliver high performance and simplify system design by integrating
functions previously implemented external to the chips. And that, in
turn, saves board space and power."
Power amplifiers in the MGA-43x28 series provide final stage gain for
Picocell and Enterprise Femtocell systems, offering 34 to 40 dB of gain
and power-added efficiency ranging from a high of 15% to 13.8%. The
power amplifiers are implemented as a three-stage design and display
performance of excellent linearity of 50 dBc adjacent-channel leakage
ratio (ACLR) at 27.3 dBm output power when biased with a 5-V supply.
The first three amplifiers in the family, MGA43428, 43528, and 43628,
are each targeted at a different frequency band-- 3GPP bands 5, 2/25,
and 1, respectively. All are fabricated using an Avago 0.25-um GaAs
Enhancement mode pHEMT process and also include a detector block
integrated on the chip. The amplifiers are packaged in a 5mm x 5mm
package that has a footprint 50% smaller than comparable devices.
The MGA-16x16 series of balanced ultra-low-noise amplifiers include
integrated active biasing and a shutdown functionality. They are ideal
solutions for cellular infrastructure applications such as base station
transceiver cards, remote radio heads, tower-mounted amplifiers and
base station combiners. The balanced LNAs deliver superior return-loss
characteristics (S11, 18 dB minimum), thus improving signal quality.
Offering a noise figure as low as 0.25 dB at 900 MHz, the first three
members in the family, the MGA-16116, 16216, and 16316 are targeted for
the 450 to 1450 MHz, the 1440 to 2350 MHz, and the 1950 to 2700 MHz
frequency bands, respectively.
Building on an Avago history of noise figure and linearity leadership
in LNAs for mobile base stations, the amplifiers have excellent gain of
18.5 dB and deliver 2X the linearity of competing devices at 19.1 dB at
900 MHz. A DC voltage applied to a control pin will shut down the
amplifier and bypass it when the system already has sufficient signal
strength, thus preventing over-amplification and signal distortion.
Also released this week is a filter-LNA module designed to simplify
portable navigation systems and embedded GPS/GNSS systems in tablets
and cell phones. The AGPS-F001 pairs a patented Avago FBAR filter with
a low-noise GaAs E-pHEMT amplifier in a single package, and continues
Avago leadership of integrated LNA/filter solutions for GPS
applications. The combination gives exceptional rejection across the
Cell/DCS/PCS/WLAN bands, ranging from 43 dBc to 53 dBc depending on the
frequency band of the signal, and linearity is 10 dBm higher in OOB
IIP3 versus competing solutions.
The AGPS-F001 has a typical noise figure of 1.7 dB, and the
noise-figure distribution is tightly controlled to ensure consistent
performance from unit to unit. A CMOS compatible shutdown pin allows
the AGPS-F001 to shut down and reduce its current draw to less than 1
uA; during normal operation the filter/amplifier draws 5.5 mA from a
2.7-V supply and provides a gain of 16.5 dB at a frequency of 1.575
GHz.
All the amplifiers and filter/amplifier are housed in small leadless
packages -- the MGA16x16 series in 4-by-4-by-0.85-mm 16-contact QFN
packages, the MGA43x28 series in 5-by-5-by-1-mm 28-contact QFN
packages, and the AGPS-F001 in a 2.3-by-1.7-by-0.9 mm 6-contact QFN
package. Samples of all devices will be available in June, with
production quantities available in the fourth quarter of 2012.
Live demonstrations of the power amplifier and filter/LNA products will
take place at the Avago booth #1909 at the IMS2012 conference in
Montreal, Canada. Many other previously released wireless products --
gain blocks, LNAs, EpHEMT amplifiers, FBAR filters, WaferCap wafer
scale packages, and integrated modules -- will also be displayed at the
booth. For additional information on these and other Avago wireless
products, go to www.avagotech.com/rf.
