Business Wire
WJ Communications, Inc. (NASDAQ:WJCI), a leading designer and
supplier of radio frequency (RF) products and solutions for the
wireless infrastructure and radio frequency identification (RFID)
reader markets, today announced the availability and production
release of the WJA1001 � the latest addition of its +5V Active Bias
General Purpose Gain Block amplifier series. The WJA1001 of the WJA
family is a high-performance broadband amplifier offering high
linearity, and housed in a low-cost surface-mount package. The
WJA1001 is a low-cost, cascadable, gain-block amplifier utilizing
the high-reliability InGaP/GaAs HBT process technology, and is
suitable for current and next generation wireless applications such
as GSM, PCS, CDMA, W-CDMA, WiBro and WiMAX, Repeaters, BTS
Transceivers, and RFID. The amplifier has been optimized to offer
industry-leading linearity performance for the 1GHz cellular band
frequency. The WJA1001 provides an excellent mix of power gain,
linearity, and supply current performance, enabling designers to
integrate with their designs. In addition, 50 ohm internal matching
minimizes the use of external components thus simplifying system
integration. "Over the past year, the WJA series has given our
customers a wide variety of high-performance and low-cost RF and IF
amplifiers empowering engineers to meet and exceed product
specifications as never before. The WJA1001 is another step in this
direction,� said Rufino Olay, Director of Worldwide Marketing at WJ
Communications. �The WJA1001 is ideal for high volume, cost
sensitive wireless applications.� Product Overview The WJA1001 is a
broadband amplifier utilizes advanced InGaP/GaAs HBT technology and
has been optimized internally to offer very high linearity
performance at 1 GHz, while drawing very low current. The MMIC
amplifier is internally matched to 50 ohm and only requires
DC-blocking capacitors and a bias inductor for operation. The
amplifier features high-cascadable gain with 19 dB gain at 900 MHz,
a +20 dBm 1-dB compression point and +45 dBm OIP3 at 900MHz while
drawing only 100mA of current with operation directly from a +5V
supply voltage. The device is ideal for wireless applications and
is available in a low-cost, surface-mount lead-free / green /
RoHS-compliant SOT-89 package. The WJA1001 is designed as a
Darlington-pair amplifier configuration and is ideal for
general-purpose pre-driver applications within the 50 to 3000 MHz
frequency range. Value Proposition Responding to market needs for
gain block amplifiers with high linearity and low current, the
WJA1001 reflects these inputs by concurrently lowering the overall
total cost of ownership and maintaining industry-leading linearity
performance for a gain block amplifier. The following are key
features of the WJA1001: -- � High Dynamic Range: � -- Diverse
applications from 50 to 3000 MHz frequency � -- High Linearity: �
-- Provides excellent linearity, 45 dBm OIP3 performance � -- Low
Current: � -- Low current consumption: 100mA � -- SMT Package: � --
Lead-free / green / RoHS-compliant SOT-89 package Positive Market
Feedback The WJA1001 is presently sampling with key strategic
customers; the customers� feedback has been very positive with
special emphasis on WJA�s high performance and cost-saving
benefits. Target Applications The WJA1001 is targeted in various
usages of current and next generation wireless technologies such as
GSM, CDMA, W-CDMA, WiBro and WiMAX. Availability & Pricing
