PMC-Sierra Expands WiMAX RF IC Solutions with New Multi-Band Devices for Global Spectrum Coverage
September 29 2008 - 5:05AM
Business Wire
PMC-Sierra, Inc. (Nasdaq:PMCS) today added four new multi-band
devices to its WiZIRD� family of highly integrated WiMAX� RF IC
solutions for Broadband Wireless Subscriber equipment. These new
devices enable WiMAX system designers to leverage a single radio
design to provide Customer Premises Equipment (CPE) and Network
Interface Cards (NICs) for all popular broadband wireless radio
bands (450-928 MHz, 2.3-2.7 GHz, 2.7-2.9 GHz, 3.3-3.8 GHz and
4.9-5.95 GHz, see Figure 1) for worldwide WiMAX deployments.
PMC-Sierra�s WiZIRD family is the industry�s most versatile and
complete WiMAX RF IC portfolio (see Figure 2), providing cost and
performance flexibility in addressing global spectrum challenges.
Multi-Band Capability Addresses Fragmented Global Spectrum
Challenges WiMAX is fast emerging as a technology of choice for
broadband access in developing economies and greenfields such as
India, Russia, Latin America, and the Middle East. However, the
lack of global spectrum policy has led to a fragmented spectrum and
added complexity for system vendors and carriers. For example, the
Government of India recently announced its policy and guidelines
for a WiMAX spectrum, establishing plans for an auction in the 2.3
and 2.5 GHz bands for broadband wireless data services and
provisions for future auctions of the 700 MHz and 3.3-3.6 GHz bands
when available.�In addition, the existing 2.7-2.9GHz spectrum is
being selected for WiMAX services. Indian carriers planning WiMAX
deployments will require cost-effective and future-proof solutions
with spectrum flexibility. OEMs can leverage the PMC-Sierra WiZIRD
family�s multi-band support to enable an ecosystem of WiMAX
equipment for broadband coverage in global markets, reducing cost
and time-to-market. OEMs can further enhance return on investment
by aggregating volume over different frequency bands and
applications through common BOM. A multi-band design also addresses
future demand for roaming-ready NIC applications. �PMC-Sierra has
long-standing relationships with telecom equipment providers and
carriers, and they have identified that one of their biggest
concerns is reach,� said Tom Sun, vice president and general
manager for PMC-Sierra�s Broadband Wireless Division. �PMC-Sierra
has made great efforts in driving RF IC innovations that extend the
reach and reliability of wireless links to enable high-performance
WiMAX equipment.� �With their new range of WiMAX 802.16e (Rev-e)
radio frequency solutions, PMC-Sierra confirms that they are major
partners of Alcatel-Lucent�s Open CPE Program,� said Karim El
Naggar, vice president and head of Alcatel-Lucent�s WiMAX
activities. �Their capability to design multi-band devices will
further accelerate the availability of WiMAX solutions for diverse
WiMAX markets, and in particular 700MHz solutions for new
applications and developing economies. Alcatel-Lucent is the
world�s leading provider of innovative WiMAX and wireless broadband
network solutions,� he continued. PMC-Sierra added the following
software compatible devices to its WiZIRD portfolio: PM8850 � Two
transmit and two receive branches (2Tx/2Rx) with multi-band support
for 2.3-2.9 GHz, 3.3-3.8 GHz and 4.9-5.95 GHz (see Figure 3).
PM8851 � One transmit and two receive branches (1Tx/2Rx), with
multi-band support for 2.3-2.9 GHz, 3.3-3.8 GHz and 4.9-5.95 GHz.
PM8870 � 2Tx/2Rx with multi-band support for 2.3-2.9 GHz, 3.3-3.8
GHz and 450-928 MHz (see Figure 4). PM8871 � 1Tx/2Rx with
multi-band support for 2.3-2.9 GHz, 3.3-3.8 GHz and 450-928 MHz.
PMC-Sierra�s WiZIRD family features the industry�s highest density
WiMAX RF IC solutions, integrating conversion ZIF RF transceiver,
analog and digital converters, and an industry-standard JEDEC
JESD207 compliant baseband digital interface. The devices use an
innovative harmonic canceling technique to achieve extremely linear
output at high power levels and deliver up to 64QAM modulation for
Tx paths at 0dBm output power level with an EVM rating that
addresses a complete spectrum of WiMAX solutions, from base station
applications to mobile subscriber solutions. The devices feature:
Low-power receivers and transmitters; Direct-conversion ZIF design;
Patent-pending integrated DC Offset algorithm that performs DC
Offset correction every frame, minimizing drift over temperature;
Support for 802.16e-2005 and 802.16-2004 IEEE standards;
Configurable channel bandwidths of 3.5 MHz, 5 MHz, 7 MHz, 8.75 MHz,
10 MHz, 14 MHz and 20 MHz; Flexible baseband device interface
options; Integrated analog-to-digital and digital-to-analog
converters; and Integrated transmitter baluns. Availability and
Customer Support PMC-Sierra�s WiZIRD PM8850, PM8851, PM8870 and
PM8871 are sampling now. The devices are implemented in CMOS
technology, packaged in a 108-pin MLF/QFN package, and rated for
industrial temperature operation (-40 to +85 degrees Celsius). A
